What you're making

This is a classic crew-neck pullover with raglan sleeves: the diagonal lines running from the neck down to the underarm. It is knitted from the top down and in one piece, which makes it one of the friendliest first sweaters:

  • No seams. There is nothing to sew together at the end.
  • You can try it on as you go. Slip it over the wearer's head once the yoke is done and check the fit before committing to sleeve or body length.
  • Almost all of it is plain knitting in the round. Once the neck is joined, you knit every stitch of every round, with a simple increase at four fixed points.

The order of work is: neck → a few flat rows to raise the back of the neck → join and knit the yoke in the round, growing at the four raglan lines → park the sleeve stitches on scrap yarn → knit the body straight down → knit each sleeve → pick up stitches and knit the neckband last.

Who this size fits

50 inches is the finished chest of the sweater. It's designed to be worn with roughly 8–10 inches of ease, so it suits a man with an actual chest measurement of about 40–42 inches who likes a comfortable, slightly roomy pullover. If the wearer measures 44 inches or more, consider the X-Large pattern numbers instead.

Shopping list

Yarn

1,260 yards of medium-to-heavy worsted weight yarn (yarn-weight category 4, sometimes labelled "aran" or "heavy worsted"). Buy one extra skein: running short in the last sleeve is the most common beginner heartbreak, and unopened skeins can usually be returned.

  • Check every skein has the same dye lot number on the label. Different lots can differ subtly in shade.
  • Wool or a wool blend is the most forgiving for a first sweater: it stretches, blocks beautifully, and hides small tension wobbles. A tweedy, heathered yarn (like the oatmeal in the original photo) hides them even better.
  • Avoid slippery yarns (pure cotton, silk, bamboo) and very dark colours for a first project; both make it hard to see your stitches.

Needles

This guide uses the magic loop method throughout, so the whole sweater needs just two needles:

NeedleSizeUsed for
32- or 40-inch circularUS 9 (5.5 mm)Everything in stockinette: yoke, body, both sleeves top to bottom
32- or 40-inch circularUS 6 (4 mm)Everything ribbed: hem, cuffs, neckband

The original pattern lists six needles (24-inch and 16-inch circulars plus double-points in each size) because a circular needle normally only works when the tube you're knitting is bigger around than the needle, so it steps down to shorter needles as the sleeve narrows. Magic loop reverses that: you use a needle that is far too long and pull the spare cable out through the middle of the stitches in a loop, knitting half the round on each tip. The tube can then be any size, so one long needle handles the 204-stitch body and the 44-stitch cuff alike. For a beginner it has real advantages: two needle tips instead of five loose double-points, no stitches sliding off needle ends, and only two needle changes per round, so no vertical "ladders".

Buy a needle with a supple, smooth cable and a seamless join; a stiff cable makes magic loop miserable. Modern interchangeable sets (ChiaoGoo, HiyaHiya, Knit Picks and similar) are designed for it, and let you swap the US 9 and US 6 tips onto the same cable.

These are the sizes the designer used; you will use whatever size gives you the right gauge (see Gauge swatch). If you get gauge on a US 10, you'll use US 10 and US 7 throughout.

Notions

  • Stitch markers: at least 5, with one in a different colour (it marks the start of each round).
  • Scrap yarn in a contrasting colour, about 2 yards, for holding sleeve stitches.
  • Blunt darning needle (tapestry needle) for moving stitches and weaving in ends.
  • Tape measure, scissors, and a row counter or a pencil and notepad.

Skills & glossary

Everything in this sweater uses the techniques below. Those tagged learn first you need from the very first row; practise them on your gauge swatch. Those tagged learn when you get there aren't needed until later and are easier to learn with the sweater in your hands. A two-minute video for any of these is one search away; the names here are the standard ones to search for.

Long-tail cast on learn first
Makes the first row of stitches. Leave a tail about 3 times the width of the finished edge; for the 61-stitch neck, a 40-inch tail is plenty.
Knit (k) and purl (p) learn first
The two basic stitches. Everything else is a variation.
Stockinette stitch learn first
The smooth "V" fabric of a classic sweater. Flat (back and forth): knit one row, purl the next. In the round: simply knit every round. The pattern uses both, briefly flat at the back neck and then in the round for everything else.
1 × 1 rib learn first
The stretchy edging on cuffs, hem and neck: k1, p1 repeated. On the next row or round, knit the stitches that look like knits (a "V") and purl the ones that look like purls (a bump). Move the yarn to the back before a knit and to the front before a purl, or you'll make accidental extra stitches.
kfb, "knit front and back" (the pattern calls this inc) learn first
The only increase used. Knit into the stitch as normal but don't slide it off; swing the right needle round to the back and knit into the back loop of the same stitch, then slide it off. One stitch becomes two. It leaves a small purl bump, which is what forms the decorative raglan line.
Slip marker (sm) learn first
When you reach a stitch marker, just move it from the left needle to the right needle and carry on. Never knit it.
Joining in the round learn when you get there
Bringing the two ends of a row together so you knit in a spiral. The only rule: make sure the cast-on edge is not twisted around the needle before you knit the first stitch. Lay the needle on a table and check the bumpy edge faces inward all the way round. A twist can't be fixed later.
Backward-loop (e-wrap) cast on learn when you get there
A quick way to add stitches in the middle of your work: twist a loop of working yarn onto the right needle. Used to add 13 stitches at the front neck and 10 under each arm. The cable cast on is a firmer alternative if you already know it.
Placing stitches on hold learn when you get there
Thread scrap yarn on the darning needle and pass it through each stitch as you slide it off the knitting needle. Tie the ends of the scrap yarn loosely. The stitches wait safely until you come back for the sleeves.
ssk, "slip, slip, knit" learn when you get there
A decrease that leans left. Slip one stitch as if to knit, slip the next as if to purl, then put the left needle through the front of both and knit them together. Two stitches become one.
k2tog, "knit two together" learn when you get there
A decrease that leans right. Put the needle through two stitches at once and knit them as one. Paired with ssk on the sleeves so the seam line looks symmetrical.
Picking up stitches learn when you get there
Making new live stitches along a finished edge by poking the needle through the fabric and pulling a loop of yarn through. Used for the underarms and the neckband. Pick up one full stitch in from the edge so the join is tidy.
Magic loop learn when you get there
Knitting a small tube on a long circular needle. Divide the stitches in half, pull the cable out between the two halves so it forms a loop, knit the half on the front tip, then turn the work, pull the cable through and knit the other half. You need it from the moment you start a sleeve (Step 7); the body is big enough to knit as a plain round. Keep the two "gap" points snug and shift them by a few stitches now and then so no loose column forms.
Binding off loosely learn when you get there
Finishing the edge so it can't unravel. Loosely matters at the neck (it has to stretch over a head) and at the hem and cuffs. Use a needle two sizes larger for the bind-off row, or learn the "stretchy bind off" (k2tog through the back loop).
Weaving in ends and blocking learn when you get there
Hiding yarn tails inside the fabric with the darning needle, then washing and laying the sweater flat to dry to even out the stitches.

Gauge swatch: don't skip this

Gauge is how many stitches you make per inch. The whole sweater is calculated on 16 stitches = 4 inches (4 stitches per inch) in stockinette on the larger needle. If your knitting is even a little tighter or looser, the sweater comes out a different size:

Your swatch measuresSts per inchBody 204 sts becomesFix

  1. With the US 9 needle, cast on 26 stitches.
  2. Work stockinette flat (knit a row, purl a row) until the piece is about 5 inches tall. Bind off.
  3. Wash it the way you'll wash the sweater and let it dry flat. Yarn relaxes when washed and the sweater will too.
  4. Lay it flat without stretching. Place a ruler across the middle (not at the edges) and count the stitches in 4 inches. Count half-stitches too.
  5. Not 16? Change needle size and knit another swatch. Two swatches take an evening; a sweater that doesn't fit takes a month.

While the swatch is out, count rows in 4 inches as well and write it down. The pattern never gives a row gauge (it measures length in inches instead), but knowing yours helps you plan the sleeve decreases in Step 7. Most knitters get roughly 22–24 rows in 4 inches with this yarn; this guide assumes about 6 rounds per inch where it estimates round counts.

Flat swatch, round sweater

The pattern's gauge is measured knitting in the round, and many knitters purl a touch looser than they knit, so a flat swatch can read slightly different. For a beginner a flat swatch is fine. A belt-and-braces check: once the yoke is joined (Step 3), measure your gauge again directly on the sweater after 3 inches. It's early enough to restart painlessly if it's off.

STEP 1

Cast on at the neck

Use the US 9 long circular. You'll cast on 61 stitches in five groups, placing a stitch marker between each group. Cast on firmly; this edge becomes the neck opening and a loose one stretches out.

The 61 cast-on stitches, seen from the outside of the sweater. The markers are the four raglan lines. The two tiny 2-stitch groups are the beginnings of the front; the rest of the front neck is cast on later, in Step 3.

  2. Cast on 15 stitches. Place a marker.
  3. Cast on 27 stitches. Place a marker.
  4. Cast on 15 stitches. Place a marker.
  5. Cast on 2 stitches.

Do not join into a round. For the next few rows you'll knit back and forth like a scarf.

STEP 2

Shape the back neck (flat rows)

The designer warns that these first rows "may be confusing", and she's right, so here's what is happening: on a real sweater the back of the neck sits higher than the front. You create that by knitting a few rows only across the back and sleeves before the front neck stitches even exist. Each right-side row grows the work by 10 stitches: one at each end of the row and one on both sides of every marker.

You'll work 9 rows in total: five increase rows (rows 1, 3, 5, 7, 9) with a plain purl row between each.

Row 1 (right side): increase row

  1. kfb into the first stitch, then kfb into the next stitch (that's the last stitch before the first marker).
  2. Slip the marker. kfb into the stitch right after it.
  3. Knit along until one stitch remains before the next marker. kfb into that stitch. Slip the marker. kfb into the next stitch.
  4. Repeat step 3 at each remaining marker.
  5. After the last marker: kfb, then kfb into the very last stitch.

That's 10 increases: one in the first stitch, two at each of the four markers, and one in the last stitch. (With only 2 stitches in each front group, the "stitch before the first marker" is simply the second stitch of the row, so the row starts kfb, kfb, slip marker, kfb.) The simplest way to hold it in your head: kfb in the first stitch, kfb in the last stitch, and kfb in the stitch on each side of every marker.

Row 2 (wrong side)

Purl every stitch, slipping the markers as you come to them.

Row 3 (right side): increase row

Exactly the same as Row 1: kfb in the first stitch; kfb in the stitch before and the stitch after every marker; kfb in the last stitch. (The pattern phrases it slightly differently but the stitches are identical.)

Repeat rows 2 and 3 until you have completed 5 increase rows and the back section (between the second and third markers) has 37 stitches. You finish on a right-side increase row.

Hold the work up: it should look like a wide, shallow U, deeper at the middle (the back) and with the two front edges angling up.

Common mistake

Forgetting the kfb in the first or last stitch. It's easy to remember the markers and miss the edges. If your total after an increase row is 8 more instead of 10, that's why. Just add the missed kfb on the next increase row; nobody will ever see it.

STEP 3

Cast on the front neck and join into the round

You've just finished row 9 and the working yarn is at the end of the row. Now you fill in the front of the neck and close the circle.

  1. With the backward-loop method, cast on 13 stitches onto the right-hand needle. You now have 124 stitches — and all of them are on that one needle tip; the other tip is empty.
  2. Lay the needle flat and check the cast-on edge runs around the inside of the circle with no twist.
  3. Place your different-coloured marker on the right needle. This marks the beginning of every round from now on, and it sits at the centre front.
  4. Slide the stitches along the cable until the stitch at the start of the row you just worked sits on the empty tip. That tip now goes in your left hand; the working yarn and the 13 new stitches stay on the right tip. Don't turn the work. The 124 stitches now form a complete ring: left tip, round the cable, back to the right tip.
  5. Bring the needle tips together and knit that first stitch off the left tip. The round is joined. Give the yarn a firm tug on this first stitch to avoid a gap.
  6. Knit one full round plain, slipping all five markers.
You are not knitting back into the new stitches

The stitch that closes the round is at the far end of the flat piece, not one of the 13 you just cast on. Remember that both ends of the Step 1 cast-on were 2-stitch front groups, now grown to 12 each: they are the two sides of the neck opening, and the 13 new stitches bridge the gap between them. That is why the front comes to 12 + 13 + 12 = 37, matching the back exactly. You are closing a horseshoe into a ring.

Stitch check
Front (both halves + 13)37Sleeve25Back37Sleeve25Total124

Front and back are now equal at 37, which is exactly how a raglan should be. If the front is not 37, recount the cast-on.

STEP 4

Knit the raglan yoke in the round

This is the rhythm of the sweater and it's very simple. You alternate two rounds:

Increase round

Knit until one stitch before a raglan marker, kfb, slip the marker, kfb. Do this at all four raglan markers. Do not increase at the beginning-of-round marker (the different-coloured one); just slip it. 8 stitches added.

Plain round

Knit every stitch.

Repeat these two rounds until the back section has 91 stitches. That is 27 increase rounds (54 rounds total). Use a row counter or tally marks; it's easy to lose your place in a plain round.

25877587324
27917991340

A useful rule: after any increase round, back = 37 + 2 × (increase rounds done), and the total is 124 + 8 × (increase rounds done). If the numbers don't match, you probably missed one marker on a round; add the missing kfb next time.

Stitch check at the end of the yoke
Front91Sleeve79Back91Sleeve79Total340

Measured straight down from the cast-on edge at the shoulder, the yoke should be roughly 10–11 inches deep. Try it on now: the raglan lines should end right at the underarm. If they're clearly short of the armpit, work one or two more pairs of rounds (the extra stitches just make the sweater a touch roomier); if they're past it, you've probably done too many. This is the last easy point to adjust.

STEP 5

Divide for the sleeves

Now you park the two sleeves on scrap yarn and cast on a few stitches under each arm, so you can carry on with the body alone. Thread your darning needle with a yard of scrap yarn before you start. From here on, remove each raglan marker as you reach it; their job is done.

  1. From the beginning-of-round marker, knit across the front stitches to the first raglan marker. Remove the marker and knit 1 more stitch.
  2. Slip the next 78 stitches (everything up to the next marker) onto the scrap yarn, using the darning needle. Remove that marker. Tie the scrap yarn ends loosely. That's one sleeve on hold.
  3. With the backward-loop method, cast on 10 stitches onto the right needle. This bridges the underarm.
  4. Knit across the 91 back stitches to the next marker. Remove it and knit 1 more stitch.
  5. Slip the next 78 stitches onto a second length of scrap yarn. Remove the last raglan marker.
  6. Cast on 10 stitches, but this time place a marker after the 5th. This new marker is your beginning of round; it sits in the middle of the left underarm.
  7. Knit to the old beginning-of-round marker at centre front and remove it. Keep knitting round to the new marker.
Stitch check
On the needle (body)204Each sleeve on scrap yarn78

204 body stitches ÷ 4 per inch = 51 inches around. The pattern's "50-inch" finished chest is this measurement rounded; you're right on target.

Why "knit 1" after removing the marker?

The designer moves one stitch from each sleeve edge onto the body so the raglan line finishes cleanly at the underarm rather than being split when you rejoin the sleeve. That's why each sleeve holds 78, not 79.

STEP 6

Body

The easy stretch. Knit every round on the 204 stitches, still on the US 9 long circular, until the sweater measures 24½ inches from the top of the shoulder. That's the cast-on edge at the point where a shoulder seam would be, straight down to the needle, with the sweater laid flat and unstretched. Total finished length is 27 inches; the last 2½ inches will be ribbing.

For a shorter or taller man, knit to 2½ inches less than the length he wants instead. The easiest way to decide is to measure a sweater he already likes, from the top of the shoulder to the hem.

Hem ribbing

  1. Change to the US 6 long circular (the smaller one). Just start knitting off the old needle onto the new one; after one round all the stitches have moved across. With interchangeable tips, simply swap the US 9 tips for US 6.
  2. Work k1, p1 around for 2½ inches. 204 is an even number, so the rib lines up perfectly at the marker every round.
  3. Bind off loosely in rib (knit the knits and purl the purls as you bind off). A tight hem pulls in and looks pinched.

STEP 7

Sleeves (make two the same)

Pick up the sleeve

  1. Slip the 78 held stitches from the scrap yarn onto the US 9 long circular. Pull the scrap yarn out once they're all safely on.
  2. With the outside of the sweater facing you, join a new strand of yarn at the right-hand edge of the underarm (leave a 10-inch tail; you'll use it to close any hole later).
  3. Pick up 12 stitches across the underarm: one in the gap at the corner, one in each of the 10 cast-on stitches, one in the far gap. Place a marker after the 6th picked-up stitch. That marker is the beginning of the round, right in the middle of the underarm.
  4. Set up the magic loop. 90 stitches won't reach round a long cable, so slide them to the middle of the cable, find the halfway point (45 stitches, roughly the top of the shoulder) and pull a loop of cable out there. You now have 45 stitches on each tip. Knit the half on the front tip, turn, pull the cable through, knit the other half; that's one round. Keep working this way all the way to the cuff; the loop just gets longer as the sleeve narrows.

Shape the sleeve

  1. Knit 3 rounds plain.
  2. Decrease round: k1, ssk, knit until 3 stitches remain before the marker, k2tog, k1. (2 stitches removed.)
  3. Knit 1 round plain.
  4. Repeat the decrease round and plain round 3 more times. You've now done 4 decrease rounds; 82 stitches. This quick run of decreases takes the fullness out of the underarm.
  5. From here, work the decrease round every 5th round: 4 plain rounds, then a decrease round, and repeat.
  6. Continue until the sleeve measures 17 inches from the underarm, or, better, until it reaches the wearer's wrist bone when tried on. The cuff adds 2½ inches beyond that.

≈ 100≈17 in reached (at 6 rounds/in)≈ 46

At around 6 rounds per inch you'll fit about 18 more decrease rounds before 17 inches, leaving roughly 46 stitches. Your row gauge will vary this by a few stitches, and that's fine: the next step evens it out.

Cuff

  1. Decrease evenly to 44 stitches on the next round:
    • 46 sts: (k21, k2tog) × 2
    • 48 sts: (k10, k2tog) × 4
    • 50 sts: (k6, k2tog) × 6, then k2
    • Fewer than 46? Stop the 5th-round decreases a little earlier next sleeve; for this one, 44 or 42 sts are both fine for a cuff.
  2. Change to the US 6 long circular (or swap to US 6 tips), still working magic loop.
  3. Work k1, p1 rib for 2½ inches.
  4. Bind off loosely in rib.

Second sleeve: write down the round you were on for every decrease and the total rounds knitted. Repeat it exactly so the sleeves match.

Adjusting sleeve length

The "every 5th round" spacing is what gets a Large from 82 stitches at the upper arm to the cuff in 17 inches. For shorter arms, decrease every 4th round so the taper finishes sooner; for longer arms, every 6th round. Try the sleeve on the wearer partway down; the sweater will hang a little differently on a body than on a table.

STEP 8

Neckband

Pick one of two finishes. The ribbed crew neck is what's in the photo and is the more classic men's finish; the roll collar is even easier.

Either way, use the US 6 long circular with magic loop, with the outside of the sweater facing you. Start at the right-hand back raglan line (the one to the wearer's right, between back and right sleeve). Join the yarn there and pick up stitches around the neck in this order:

EdgePick upTip
Across the back of the neck27one in each cast-on stitch
Across the top of the left sleeve15one in each cast-on stitch
Down the left side of the front neck8one stitch in from the edge, skip about every 4th row

Up the right side of the front neck8mirror the left side
Across the top of the right sleeve15one in each cast-on stitch
Total86an even number, so 1 × 1 rib meets neatly

Place a marker and join into the round.

Option A: ribbed crew neck

Work k1, p1 rib for 1½ inches. Bind off very loosely in rib. This edge must stretch over a head: bind off with a needle two or three sizes larger, or use a stretchy bind-off. Test by pulling the neck open to about 24 inches around; it should get there without strain.

Option B: roll collar

Knit every round for 3¼ inches, then bind off very loosely. Stockinette curls naturally, so the collar rolls over on itself and shows its purl side, hiding the bound-off edge.

STEP 9

Finishing

  1. Close the underarm gaps. Turn the sweater inside out. Wherever a small hole shows at the corner of an underarm, use the yarn tail you left there to sew it shut with a couple of stitches through both layers.
  2. Weave in every end. Thread each tail on the darning needle and run it diagonally through the purl bumps on the inside for about 3 inches, then back the other way for an inch. Trim, leaving a ½-inch stub that will disappear into the fabric.
  3. Wet block. Soak the sweater in cool water with a little wool wash for 20 minutes. Press out the water (never wring), roll it in a towel and stand on the roll, then lay it flat on a dry towel. Gently pat it to the finished measurements: 25 inches across the chest (half of 50), 27 inches long, sleeves smooth and straight. Leave it to dry fully, a day or two.

Blocking is the step that turns "hand-knit" into "hand-made". Uneven stitches settle, the raglan lines straighten and the ribbing sits flat.

Fit adjustments

The pattern is drafted for a man of average height. Everything about width is fixed by the size you chose; length is entirely in your hands, and the top-down construction means you can try on as you go.

Wearer is…BodySleeves
Shorter than averageKnit the body to 2½ in less than his preferred sweater length (say 22–23 in before ribbing instead of 24½)Decrease every 4th round; stop when the sleeve reaches the wrist bone
Average24½ in, then ribDecrease every 5th round; 17 in, then rib
Taller than averageKnit to 26 in or more before ribbing; budget an extra 50 yards of yarn per inch addedDecrease every 6th round; keep going until the wrist bone

Length changes only affect how much yarn you need; width changes need a different size. If in doubt, buy the extra skein.

Troubleshooting

My stitch count is off by 2 after an increase round.
You missed one marker (or the edge stitch, while working flat). Don't rip back. On the next increase round, add an extra kfb at the marker that's short. Check which section is low against the tables above.
The join twisted and I've knitted several rounds.
Unfortunately there's no fix but ripping back to the join. Take heart: this happens to everyone once. It's only a few rounds of the front neck.
There's a hole at each underarm.
Normal. Picking up the extra stitch in each corner gap (Step 7) shrinks it; the yarn tail closes the rest (Step 9).
The neck won't go over his head.
The bind-off is too tight. Undo just the bind-off row (it unravels easily from the end), put the stitches back on the needle, and bind off again with a needle three sizes larger.
I can see a loose vertical column on the sleeves where the magic loop cable comes out.
Pull the first two stitches on each tip snug after every turn, and every few rounds move the loop point by a few stitches so it doesn't fall in the same column. Ladders also mostly vanish with blocking.
I lost count of rounds in the yoke.
Count the back stitches instead. Back = 37 + 2 × increase rounds, so 67 back stitches means 15 increase rounds done. Count the purl bumps along a raglan line to confirm: one bump per increase round.
The sweater looks narrower than 50 inches on the needle.
It's scrunched up on the cable. Trust the stitch count and your gauge swatch; measure only after blocking.
I'm running low on yarn.
Stop and buy more before the second sleeve. If the shop has no matching dye lot, use the new lot for both cuffs and the neckband, where a slight shade change reads as intentional.
