Whether you’re making it for yourself, a loved one, or as a thoughtful handmade gift, this sweater is sure to become a staple in your wardrobe and in your creative routine.
In this post, you’ll find everything you need: materials, yarn recommendations, gauge information, sizing notes, stitch abbreviations, and the full step-by-step pattern. Let’s dive in.
Why You’ll Love This Pattern
There’s something undeniably satisfying about a striped sweater. The rhythmic color changes break up the monotony of working in a single shade, and the finished result always looks far more impressive than the effort required. Add a cozy turtleneck, a relaxed fit, and a soft yarn that feels like a hug, and you’ve got a sweater pattern that practically works itself.
This pattern is designed with accessibility in mind. The construction is top-down and worked in the round, which means no seaming at the end — always a crowd-pleaser. The stitch pattern is simple enough that you can follow along while watching your favorite show, but the stripe sequence adds enough visual interest to keep things exciting. The turtleneck is crocheted last and gives the sweater that elevated, polished look that photographs beautifully.
This is the kind of pattern that you’ll return to again and again in different colorways. Classic cream and camel, earthy olive and rust, cool blue and white, bold black and red — the combinations are endless.
Materials You’ll Need
Yarn: Choose a soft, medium-weight (size 4 / worsted weight) yarn in two or more colors. For the best drape and that signature cozy feel, look for yarns with some natural fiber content. Suggestions include:
Paintbox Yarns Simply DK (or worsted), Lion Brand Pound of Love, Drops Karisma, or any favorite acrylic-wool blend. You’ll need approximately 800–1,200 yards total depending on your size, split between your main color (MC) and contrast color (CC). If you’re making a three-color stripe, divide accordingly.
Hook: US Size J/6.0mm crochet hook (adjust as needed to match gauge)
Notions:
Yarn needle for weaving in ends, stitch markers (at least 4), scissors, measuring tape, and a scrap piece of yarn or stitch holder for live stitches
Gauge: 14 stitches x 16 rows = 4 inches in half double crochet (hdc), blocked. Gauge is important for fit, so please swatch before beginning, especially if you’re making this as a gift.

Stripe Sequence
The beauty of this sweater is its stripe pattern. You can adjust the width of the stripes to your taste, but the default sequence is as follows:
4 rounds MC, 4 rounds CC, repeat throughout the body. For the sleeves, the same sequence is maintained to keep the sweater cohesive. When changing colors, cut your yarn at the end of each stripe if you prefer cleaner edges, or carry the unused color up on the inside of the work for a more seamless transition. Either method works well; carrying up is faster, while cutting and weaving gives a tidier interior.
For a more modern, irregular look, you can try 2 rounds MC, 6 rounds CC, 4 rounds MC, 2 rounds CC, and repeat. There’s no wrong answer here — make it yours.
The Pattern
Yoke
The sweater begins at the neckline and expands outward using strategic increases to shape the raglan yoke.
With MC, make a magic ring or ch 4 and join with sl st to form a ring.
Foundation round: Ch 2 (counts as first hdc throughout). Work 59 (63, 67, 71, 75, 79, 83) hdc into the ring. Join with sl st to the top of the ch-2. You now have 60 (64, 68, 72, 76, 80, 84) stitches.
Place markers as follows to separate your four raglan sections: This sets up your left front, right front, left sleeve, right sleeve, and back panels. Divide your stitch count as follows —
Front: 14 (15, 16, 17, 18, 19, 20) sts
Back: 14 (15, 16, 17, 18, 19, 20) sts
Each sleeve: 7 (7, 8, 8, 9, 9, 10) sts
Place a stitch marker at each of the four raglan points (between front and sleeve, sleeve and back, back and sleeve, sleeve and front).
Raglan Increase Round (worked on RS): Ch 2, hdc to 1 st before marker, 3 hdc in next st, sm, 3 hdc in next st; repeat from around, hdc to end of round, join. Each increase round adds 8 stitches (2 at each of the 4 raglan points).
Repeat the raglan increase round every round for 18 (20, 22, 24, 26, 28, 30) total rounds, changing colors according to your stripe sequence every 4 rounds.
After all raglan increase rounds are complete, you will have approximately 204 (224, 244, 264, 284, 304, 324) stitches total.
Separating the Sleeves
Now you’ll place the sleeve stitches on hold and join the body into one continuous tube.
Separation Round: Ch 2, hdc across the front stitches to the first sleeve marker. Ch 4 (6, 6, 8, 8, 10, 10) (these are your underarm chains), skip the sleeve stitches and place them on a stitch holder or scrap yarn, hdc across the back stitches, ch 4 (6, 6, 8, 8, 10, 10), skip the second sleeve stitches and place them on hold, join to front stitches to close the round.
You now have the body stitches plus the underarm chains in one continuous loop.
Body
Join your stitch count into the round. You should have approximately 120 (132, 144, 156, 168, 180, 192) body stitches, including the underarm chains.
Continue working in the round in hdc, maintaining your stripe sequence, until the body measures 14 (14.5, 15, 15.5, 16, 16, 16.5) inches from the underarm, or until the sweater reaches your desired length before the ribbing hem.
Ribbing Hem: Switch to MC (or whichever color you’d like for the hem). Work 6 rounds of hdc in BLO for a subtle, stretchy ribbing effect. Alternatively, work rows of sc in BLO back and forth for a more pronounced ribbed hem — simply ch 8, sc in 2nd ch from hook and across (7 sc), then sl st into the sweater body and turn, working back the other way. Repeat until you’ve gone all the way around and seam the short ends together.
Fasten off and weave in ends.
Sleeves
Return the held sleeve stitches to your hook. With RS facing and MC, join yarn at the center underarm chain.
Set-up Round: Ch 2, hdc across the sleeve stitches, hdc into each underarm chain stitch. Join to form a round. You will have approximately 57 (61, 67, 71, 79, 83, 91) stitches.
Work in hdc in the round, maintaining the stripe sequence, and begin decreasing for the sleeve taper.
Decrease Round: Ch 2, hdc2tog, hdc to last 2 sts, hdc2tog, join. Work the decrease round every 6th round until the sleeve measures approximately 15 (15, 16, 16, 17, 17, 17) inches from the underarm.
Continue straight (without decreases) until the sleeve measures 17–18 inches from the underarm, or your desired length before cuff ribbing.
Sleeve Cuff: Work 4 rounds of hdc in BLO, or use the short-row ribbing method described for the hem. Fasten off and weave in ends. Repeat for the second sleeve.
Turtleneck
Here’s where the sweater truly comes to life. The high neck is what sets this design apart from a standard crewneck pullover, and it’s wonderfully quick to work up once the body is complete.
With MC (or CC for a color-blocked effect), and with RS facing, join yarn at the center back of the neckline.
Set-up Round: Ch 2, hdc evenly around the neckline. The exact stitch count will depend on your original foundation round — aim to keep the same stitch count as your foundation neck round (60, 64, 68, 72, 76, 80, 84 sts). Join.
Continue working in hdc in the round for 10 inches total (or your preferred height for the turtleneck). You can work it in a single color for a clean look, or continue your stripe sequence for a playful, cohesive finish. For a foldover turtleneck, work 12–14 inches — the extra length folds over beautifully.
For the final 2 rounds, switch to hdc in BLO for a smooth, stretchy edge that sits comfortably around the neck.
Fasten off and weave in all remaining ends.
Finishing
Weave in all yarn ends using your yarn needle, being sure to secure the ends well at every color change. Block your sweater by soaking it in cool water, gently pressing out the excess water in a towel (never wring), and then laying it flat to dry in the correct measurements. Blocking evens out your stitches, softens the fabric, and gives the whole garment a polished, professional appearance. This step makes a dramatic difference and is absolutely worth the extra time.
Customization Tips
One of the best things about this sweater pattern is how easily it adapts to your personal style and preferences.
Color Play: Stick with two classic neutrals for a timeless wardrobe staple. Go bold with contrasting brights. Try a tonal stripe by using two shades of the same color family — dusty rose and deep mauve, for instance, or sage green and forest green. You could even use a self-striping yarn for the main body and a solid for the turtleneck.
Yarn Swaps: While worsted weight is recommended, this pattern translates beautifully in bulky yarn on a larger hook (US L or M) for an even chunkier, faster-to-work version. If you want a lighter spring sweater, use DK weight and size down your hook accordingly, then check gauge before committing.
Length Adjustments: Add or subtract body length before the hem ribbing to create a cropped sweater or a longer tunic-style design. Similarly, sleeve length is easy to adjust — just keep working until you reach your desired measurement before adding the cuff.
Stitch Variations: The body of this sweater works beautifully in moss stitch (alternating sc and ch 1, offset each round) or even simple granny-style panels if you want more texture. Keep the yoke and collar in hdc for structure, but feel free to experiment with the body.
Notes for Beginners
If you’re newer to garment crochet, a few things will make this project much smoother. First, always make a gauge swatch. It can feel tedious, but even half an inch off per 4 inches of fabric adds up to significant differences across a sweater. A quick swatch now saves you hours of potential frogging later.
Second, use stitch markers liberally. The raglan increases require careful tracking, and a well-placed marker keeps you from losing count mid-round.
Third, don’t be afraid to try the sweater on as you go. One of the great advantages of top-down construction is that you can slip the piece over your head at any point and check the fit before you’ve committed to the full length.
Finally, remember that crochet garments often look best after a good blocking. If your finished sweater looks a little stiff or uneven fresh off the hook, don’t panic — wash it, block it to measurements, and let it dry. You’ll be amazed at the transformation.
