Whether you are an intermediate crocheter looking to level up your skills or an adventurous beginner who is not afraid of a little challenge, this pattern is designed to be approachable, detailed, and completely doable.

Let us get into it.

What Makes the Cable Stitch Turtleneck So Special?

Before we talk yarn weights and hook sizes, let us talk about why this particular design is worth your time and effort. The cable stitch in crochet mimics the beloved look of knitted cables — those thick, rope-like twists that give chunky sweaters their iconic visual texture. Traditionally, cables were considered a knitting technique, but clever crocheters have developed methods to achieve that same sculptural, three-dimensional look using a crochet hook. The result is a sweater that looks incredibly complex but is actually built from a manageable set of repeated motifs once you get the hang of them.

The turtleneck silhouette adds another layer of sophistication. It is a classic style that never goes out of fashion, works beautifully for layering during colder months, and flatters a wide range of body types. Combined with the visual weight of crochet cables, you get a sweater that is both practical and genuinely stunning.

This design from TCDDIYD is worked primarily in panels, which means you will construct the front, back, and sleeves separately before seaming them together. This approach makes it easier to keep your tension consistent and to adjust sizing as needed.

Materials You Will Need

Getting your supplies together before you start will make the entire process smoother. Here is what you will need for this project:

Yarn: You will want a medium-weight (Category 4) or bulky-weight (Category 5) yarn in a smooth, solid color. Solid colors show off cable texture far better than variegated or heathered yarns. A wool or wool-blend yarn is ideal because it has natural elasticity that helps cables pop. Acrylic yarn works perfectly well if you prefer an easy-care option. You will need approximately 800 to 1,200 yards depending on your size. Always check the yardage in the specific size you are making and add at least 10% extra.

Crochet Hook: Use the hook size recommended on your yarn’s label as a starting point. For medium-weight yarn, this is typically a 5.0mm (H/8) or 5.5mm (I/9) hook. You may need to size up slightly to keep your fabric from being too stiff, especially in the cable sections.

Cable Hook or Small Auxiliary Hook: This is used to hold stitches while you work the cable crossings. A spare hook in a smaller size works fine.

Yarn Needle: For seaming your panels together and weaving in ends.

Scissors: A sharp pair dedicated to your craft projects.

Stitch Markers: At least 10 locking stitch markers to mark cable panel positions and row beginnings.

Measuring Tape: Essential for checking your gauge and your body measurements.

Row Counter: Optional but extremely helpful when working the cable repeat rows.

Understanding Gauge

Gauge is not optional when you are making a wearable garment. Getting your gauge right is the single most important thing you can do to ensure your finished turtleneck fits the way it is intended to.

For this pattern using medium-weight yarn, you are aiming for approximately 14 stitches and 18 rows over a 4-inch square in the main stitch pattern. Work a gauge swatch of at least 6 inches by 6 inches, block it the same way you intend to block your finished sweater, and measure the center. If you have too many stitches per inch, go up a hook size. If you have too few, go down a hook size.

It can feel tedious, but a gauge swatch will save you hours of frustration and a sweater that does not fit.

Abbreviations and Stitch Guide

Here are the abbreviations used throughout this tutorial:

ch — chain
sl st — slip stitch
sc — single crochet
hdc — half double crochet
dc — double crochet
FPdc — front post double crochet
BPdc — back post double crochet
FPtr — front post treble crochet
sk — skip
st(s) — stitch(es)
RS — right side
WS — wrong side
rep — repeat
pm — place marker
sm — slip marker

Cable Cross (worked over 4 stitches): Skip the next 2 stitches, work FPtr in each of the following 2 stitches, then go back and work FPtr in each of the 2 skipped stitches, crossing in front of the stitches just worked. This creates the signature twist of the cable.

Rib Stitch: Alternating FPdc and BPdc worked over the same stitch in the previous row. This is used for the ribbed cuffs, hem, and turtleneck collar.

Sizing Information

This pattern is written for a range of sizes. Measure yourself at the fullest part of your bust and use the following guide:

Size XS fits a 32–34 inch bust. Size S fits a 34–36 inch bust. Size M fits a 36–38 inch bust. Size L fits a 38–40 inch bust. Size XL fits a 42–44 inch bust. Size 2XL fits a 44–46 inch bust.

The pattern is designed with approximately 2 to 4 inches of positive ease, meaning the finished sweater will be slightly larger than your actual measurements for a comfortable, relaxed fit. If you prefer a closer fit, size down. If you love a roomy, oversized look, stay true to size or size up.

Throughout the pattern, instructions will be written for the smallest size with larger sizes listed in parentheses in this order: XS (S, M, L, XL, 2XL).

Pattern Instructions

Part One: The Back Panel

Chain 56 (60, 64, 68, 74, 78).

Foundation Row (WS): Starting in the second ch from hook, work 1 hdc in each ch across. Turn. You should have 55 (59, 63, 67, 73, 77) stitches.

Ribbing Rows 1–10: Work in alternating FPdc and BPdc across, starting with FPdc in the first stitch. This establishes your ribbed hem. At the end of the 10th row, do not turn. Instead, rotate your work 90 degrees and work 1 sc in the side of each ribbing row up the left edge. This will help the hem lie flat and give your sweater a polished finish.

Turn and begin the main body.

Body Setup Row (RS): Ch 2, dc in each stitch across. Turn.

Row 1 (WS): Ch 2, BPdc in first 8 (10, 12, 14, 17, 19) sts, pm, hdc in next 4 sts (this is where your first cable panel will sit), pm, BPdc in next 8 sts, pm, hdc in next 4 sts (second cable panel), pm, BPdc in next 8 sts, pm, hdc in next 4 sts (third cable panel, center), pm, BPdc in next 8 sts, pm, hdc in next 4 sts (fourth cable panel), pm, BPdc in last 8 (10, 12, 14, 17, 19) sts. Turn.

Row 2 (RS): Ch 2, FPdc across to first marker, sm, work Cable Cross over next 4 sts, sm, FPdc to next marker, sm, Cable Cross over next 4 sts, sm, FPdc to next marker, sm, Cable Cross over next 4 sts, sm, FPdc to next marker, sm, Cable Cross over next 4 sts, sm, FPdc to end. Turn.

Rows 3–5: Work in established pattern with BPdc on WS rows and FPdc on RS rows, working the cable panel stitches in hdc on WS and holding the cable cross for RS rows.

Row 6 (RS): Repeat Row 2, working Cable Cross in each marked cable panel.

This 6-row cable repeat is the heart of the pattern. Continue repeating Rows 1 through 6 until the back panel measures 14 (14.5, 15, 15, 15.5, 15.5) inches from the base of the ribbing, ending on a WS row.

Armhole Shaping: On the next RS row, sl st across the first 4 (5, 5, 6, 7, 7) sts to shape the armhole, then work in pattern to the last 4 (5, 5, 6, 7, 7) sts. Leave those remaining sts unworked. Turn. Continue in pattern on the remaining stitches for the armhole section, decreasing 1 stitch at each end of every RS row 3 (3, 4, 4, 5, 5) times total. Continue even on remaining stitches until the armhole measures 8 (8.5, 9, 9.5, 10, 10.5) inches. Fasten off and set aside.

Part Two: The Front Panel

Work exactly the same as the Back Panel through the armhole shaping section. Once the armhole measures 6 (6, 6.5, 6.5, 7, 7) inches, you will begin neck shaping.

Neck Shaping: On the next RS row, work in pattern across the first 15 (16, 17, 18, 20, 21) sts for the right shoulder. Place the center 11 (13, 15, 17, 19, 21) sts on a holder or length of scrap yarn — this will become the front neck opening. Join a new length of yarn at the left side and work across the remaining 15 (16, 17, 18, 20, 21) sts for the left shoulder.

Work each shoulder separately, decreasing 1 stitch at the neck edge every row 3 times. Continue even on remaining shoulder stitches until the front armhole matches the back armhole in height. Fasten off.

Part Three: The Sleeves (Make Two)

Chain 30 (32, 34, 36, 38, 40).

Foundation Row (WS): Hdc in second ch from hook and each ch across. Turn. You have 29 (31, 33, 35, 37, 39) sts.

Ribbing Rows 1–10: Work in FPdc and BPdc rib stitch as established for the hem. This creates the cuff of your sleeve.

Sleeve Body Setup: After the ribbing, work in the main cable stitch pattern, centering one or two cable panels in the middle of the sleeve depending on your sleeve width. Work increases of 1 stitch at each end of every 6th row to shape the sleeve, maintaining pattern as you increase. Continue until the sleeve measures 17 (17.5, 18, 18, 18, 18) inches from the end of the ribbing, or your desired sleeve length minus the cuff ribbing.

Sleeve Cap Shaping: Sl st across the first 4 (5, 5, 6, 7, 7) sts, work across to last 4 (5, 5, 6, 7, 7) sts. Leave those unworked. Decrease 1 stitch at each end every RS row until you have 11 (11, 13, 13, 15, 15) sts remaining. Work 2 rows even. Fasten off.

Part Four: Assembly

Block all four pieces before seaming. Pin them to your blocking mats or a clean towel in their correct measurements and mist with water, or steam lightly if your yarn tolerates it. Allow to dry completely. This step makes seaming dramatically easier and gives the cables that beautiful, defined texture you see in finished photos.

With your yarn needle and a length of yarn, seam the right shoulder using a mattress stitch or whip stitch, whichever you prefer. Seam the left shoulder the same way.

Set in each sleeve by pinning the center of the sleeve cap to the shoulder seam, then easing the sleeve evenly into the armhole before stitching. Seam the side seams and the sleeve seams in one continuous line for a clean finish.

Part Five: The Turtleneck Collar

This is where the sweater really comes to life. The tall, cozy turtleneck collar is worked in the round directly from the neck opening.

With the RS facing and starting at the right shoulder seam, pick up and work 1 sc in each stitch and 1 sc in the side of each row around the entire neck opening. Join with sl st to the first sc. You want approximately 60 to 72 stitches total for the collar, adjusted to a number that works evenly with your rib repeat. Place a marker at the beginning of the round.

Round 1: Work in FPdc and BPdc rib stitch around. Join with sl st.

Repeat Round 1 until the collar measures 9 to 11 inches from the pick-up round, or your desired turtleneck height. The collar is intentionally tall so it can be folded over once for a classic double-fold turtleneck look, or worn straight up for maximum warmth and drama.

When the collar is complete, finish with 1 round of sc and fasten off. Weave in all your ends securely.

Finishing Touches

After assembly, give your turtleneck one final block as a complete garment. This unifies all the pieces and evens out any seams. Turn the collar down into its folded position and pin it while it dries to train the fold into place.

If you notice any gaps at the underarms after seaming, use a few whip stitches with the yarn tail to close them. Trim all ends close to your weave-in points, taking care not to cut the working yarn.

Tips for Success

Cable stitches require a bit of practice before they start feeling natural, so do not be discouraged if your first cable crossing feels awkward. Work a sample swatch of just the cable panel repeat until the motion becomes muscle memory. Most crocheters find that by the third or fourth cable repeat, the technique clicks into place.

Keeping consistent tension is especially important in post-stitch work. FPdc and BPdc pull against the fabric differently than regular stitches, so take care not to crochet too tightly in these sections. If your post stitches look distorted or the fabric is puckering, loosen your tension gradually until the surface lies smooth.

If you want to customize the length of this sweater, simply work more or fewer rows in the main body before beginning armhole shaping. You can turn this into a cropped sweater by working the body to about 10 inches, or extend it into a tunic by going to 18 to 20 inches.

For color variations, a deep jewel tone like burgundy, forest green, or navy will make those cables absolutely sing. Neutral tones like cream, oatmeal, or charcoal gray give it a more classic, timeless look.

Why You Will Love This Pattern

The cable stitch turtleneck sits in a sweet spot between genuinely impressive and genuinely achievable. It looks like a sweater that belongs in a boutique window or on a magazine cover, but it is built from techniques that any dedicated crocheter can master with a little practice and patience. The panel construction means you can pick up and put down individual sections without losing your place in a complex all-in-one construction. The cable repeat is short enough to memorize quickly, which means this becomes a satisfying project you can work on while watching your favorite shows without losing count.

More than anything, the end result is a piece you will actually wear — warm, stylish, and made entirely by your own hands. There is no better feeling than
