Cozy Crochet Mohair Sweater Pattern Perfect for Autumn Time Wear
There is something deeply satisfying about wrapping yourself in a sweater you made with your own hands. The weight of it, the texture, the way it drapes just the way you imagined it would when you first wound the skein around your fingers and thought, this is the one. When autumn arrives and the air shifts from warm to something crisper and golden, that satisfaction becomes something even more personal. You are not just wearing a sweater. You are wearing the hours you spent, the patience you practiced, and the creativity you poured into every stitch.
Mohair is, without question, one of the most beautiful yarns you can work with for a project like this. It has a halo — that soft, cloud-like fuzz that surrounds the strand — that gives finished pieces a dreamy, elevated look. Mohair sweaters have had a serious moment in fashion over the past several years, turning up on runways and in autumn lookbooks everywhere. But the truth is, a handmade crochet mohair sweater will always outshine anything you find on a rack, because it fits your body, reflects your style, and carries something no store-bought piece ever could.
This pattern is designed for crocheters who are comfortable with the basics — chain stitches, single crochet, half double crochet, and joining rounds — but it is written with enough detail that an adventurous beginner who has finished a few small projects could absolutely follow along. The finished sweater is relaxed and slightly oversized, with a wide round neck, dropped shoulders, and long sleeves. It is the kind of sweater you will reach for on every cool morning between September and November. The kind you wear with jeans and boots to a pumpkin patch, or over a turtleneck while you read by the window with a mug of something warm.
Materials You Will Need
Before you begin, gather everything so your workspace is ready. There is nothing more frustrating than getting deep into a crochet project and realizing you are short a skein.
For yarn, you want a kid mohair and silk blend held together with a fine or fingering weight silk or cotton thread. The most popular choice in this style of pattern is a kid mohair-silk blend like Drops Kid-Silk, Rowan Kidsilk Haze, or a similar yarn from your local craft store. You will hold two strands together throughout the entire project, which gives the fabric both structure and that gorgeous airy halo. You will need approximately 1,200 to 1,600 yards of mohair yarn depending on your size, and roughly the same amount of your holding yarn.
For the hook, a 6mm or 6.5mm crochet hook works beautifully with this double-strand combination. The larger hook creates an open, drapey fabric that lets the mohair halo breathe and bloom. If you tend to crochet tightly, go up to a 7mm. If your swatches come out loose and floppy, drop down to a 5.5mm.
You will also need stitch markers (at least six to eight), a yarn needle for weaving in ends, scissors, and a measuring tape. Optional but helpful are locking stitch markers or safety pins, a blocking mat, and rust-proof pins for finishing.
Gauge and Sizing
Getting your gauge right before starting a sweater is one of the most important steps you can take to ensure the finished piece actually fits the way you want it to. I know, I know — swatching is the least exciting part. But with mohair especially, the gauge can shift quite a bit depending on your tension, your hook size, and even how much humidity is in the air.
To make your gauge swatch, chain 20 and work in half double crochet for 20 rows. Block your swatch gently by misting it with water and pressing it flat with your hands. Let it dry completely, then measure the center of the swatch. You are looking for 12 stitches and 10 rows to equal 4 inches (10 centimeters) in half double crochet with your yarn held double and your chosen hook.
This pattern is written in five sizes. The finished bust measurements are as follows: Small (36 inches), Medium (40 inches), Large (44 inches), Extra Large (48 inches), and Double Extra Large (52 inches). Throughout the pattern, stitch counts and any size-specific instructions will be listed in order, like this: S (M, L, XL, XXL). Always identify your size before you begin and circle or highlight those numbers throughout to avoid confusion.
The sweater is designed with about 4 to 6 inches of positive ease, meaning it will be noticeably relaxed on the body. This is intentional. Mohair sweaters look their absolute best with a little room to breathe, and this silhouette is meant to be cozy rather than fitted.

The Pattern: Step by Step
The Back Panel
Begin with a foundation chain. Chain 55 (61, 67, 73, 79).
Row 1 (RS): Starting in the third chain from the hook (the skipped chains do not count as a stitch), work one hdc in each chain across. You should have 53 (59, 65, 71, 77) hdc. Turn.
Row 2: Chain 2 (does not count as a stitch throughout), hdc in each stitch across. Turn.
Repeat Row 2 until the piece measures 14 (14.5, 15, 15, 15.5) inches from the foundation edge, or until you reach your desired body length to the underarm. This is a good place to try the piece on by holding it up to your body — you want it to land at or just above your natural waist before the yoke begins.
Fasten off and leave a tail for seaming.
The Front Panel
Work the front panel exactly as you worked the back panel. You will seam them together at the shoulders later, so keeping both pieces identical at this stage simplifies construction beautifully.
Fasten off and leave a tail for seaming.
Joining at the Shoulders
Lay your back panel flat with the right side facing up. Place the front panel on top of it, right side facing down, so that the right sides are facing each other. Align the edges carefully.
Using your yarn needle and a length of yarn, seam the shoulders together using a whip stitch or mattress stitch. For a Small, leave the center 8 to 9 inches open for the neck. For Medium and Large, leave the center 9 to 10 inches open. For XL and XXL, leave 10 to 11 inches open. The shoulder seams on each side should measure approximately 3 to 4 inches.
If you prefer a cleaner join, you can use a slip stitch seam with your crochet hook. Simply align the edges, insert your hook through both layers, and slip stitch across. This method is faster and creates a slightly more structured shoulder line.
Sleeve Construction
This sweater uses top-down sleeve construction, meaning you will pick up stitches around the armhole opening rather than working separate sleeves and seaming them in. This approach gives a cleaner finish and is actually easier than it sounds.
With your sweater assembled at the shoulders, identify the armhole opening. You want the armhole to measure approximately 8 (8.5, 9, 9.5, 10) inches from the shoulder seam down each side. Place stitch markers at those points on both the front and back panels to designate the armhole.
Join your yarn at the shoulder seam with a slip stitch. Chain 2 and work hdc evenly around the armhole opening. The exact number of stitches will depend on your row gauge, but aim for approximately 48 (52, 56, 60, 64) stitches total around the armhole. Join with a slip stitch to the first hdc to form a round. You are now working in the round.
Round 1: Chain 2, hdc in each stitch around. Join.
Continue working rounds of hdc until the sleeve measures 5 inches from the armhole.
Sleeve Decrease:
Begin decreasing for the tapered sleeve on the next round. Work as follows: Ch 2, hdc2tog (half double crochet two together), hdc in each stitch across until 2 stitches remain, hdc2tog. Join. You have decreased by 2 stitches.
Repeat this decrease round every 6th round until you have 28 (30, 32, 34, 36) stitches remaining, or until the sleeve measures approximately 17 to 18 inches from the armhole (adjust for your arm length as needed).
Work even in hdc without decreasing until the sleeve reaches your desired total length. Most people find a sleeve length of 19 to 21 inches from the armhole works well, but crochet is flexible — try it on and make it your own.
Sleeve Cuff:
For the cuff, switch to working in BLO (back loop only) for a ribbed effect.
Round 1 (Cuff): Ch 1, sc in BLO in each stitch around. Join.
Repeat this round for 8 to 10 rounds total. The back loop single crochet creates a subtle texture that mimics ribbing and hugs the wrist softly. Fasten off and weave in ends.
Repeat the sleeve construction for the other armhole.
Side Seams
With both sleeves complete, it is time to close the side seams of the body. Fold the sweater so that the front and back panels are aligned with right sides facing each other. Seam from the bottom hem up to the armhole marker on each side using your preferred method. Weave in all ends as you go.
Neck Finishing
The neck on this sweater is intentionally relaxed and wide, requiring minimal finishing. Join your yarn at any point along the neck opening with a slip stitch.
Round 1: Chain 1, work sc evenly around the neck opening, placing a stitch marker at each shoulder seam to help keep things even. Join with a slip stitch.
Rounds 2 and 3: Ch 1, sc in each stitch around. Join.
If you want a slightly more structured neckline, work 2 additional rounds of sc in BLO for a gentle ribbed trim. Otherwise, fasten off after Round 3 and weave in your end.
Hem Finishing
Turn the sweater right side out and join yarn at the side seam at the bottom hem.
Round 1: Ch 1, sc evenly around the entire hem. Join.
Rounds 2 and 3: Repeat as for the neck.
You can also leave the hem completely unfinished for a more casual, raw edge look — mohair has enough body that it will not curl or unravel, so this is a perfectly valid aesthetic choice.
Blocking Your Finished Sweater
Blocking is what takes a handmade crochet project from looking homemade to looking handcrafted. With mohair especially, blocking is transformative. The fibers bloom, the stitches even out, and the halo becomes even more pronounced and beautiful.
Fill a basin or sink with cool water and a small amount of gentle wool wash or baby shampoo. Submerge your sweater completely and let it soak for 20 minutes. Do not agitate or wring — simply press the water through the fibers gently. Lift the sweater out supporting its full weight (wet mohair is heavy), and press it against the side of the basin to remove excess water. Roll it in a clean towel and press firmly to absorb more moisture.
Lay your sweater flat on a blocking mat and pin or shape it to your desired measurements. Check the finished dimensions against your size measurements and coax the sweater into shape with your hands. Allow it to dry completely before wearing — this may take 24 to 48 hours depending on your climate.
Caring for Your Mohair Sweater
Mohair is a delicate fiber and deserves gentle care. Always hand wash in cool water or use a wool-friendly machine cycle if your washing machine has one. Dry flat every time — never hang a mohair sweater, as the weight of wet fibers will stretch it out of shape. Store it folded in your drawer rather than on a hanger for the same reason.
If your sweater begins to pill over time, use a fabric shaver or a fine-tooth comb to gently remove the pills. Mohair can also flatten over time, but a gentle steam from an iron held a few inches above the surface — never directly touching — will restore the halo beautifully.
Styling Ideas for Autumn
The beauty of a sweater like this is how many different ways it can carry you through the season. On its own over straight-leg jeans and ankle boots, it is effortlessly put-together. Layered over a thin turtleneck or mock-neck, it becomes something more polished and intentional. Belted loosely at the waist, it takes on a completely different silhouette. Worn oversized with bike shorts and sneakers, it enters cozy-cool territory that autumn weekends are made for.
The colors of mohair yarn available today are extraordinary. If you want to lean into autumn fully, consider burnt oranges, deep terracottas, warm taupes, mushroom browns, or forest greens. For something more unexpected, a dusty rose or slate blue mohair sweater in autumn is genuinely stunning — the softness of the fiber against the crispness of the season creates a contrast that feels intentional and beautiful.
A Few Tips Before You Begin
Working with mohair held double can feel slippery and slightly tricky at first, especially if you are used to more structured fibers. Go slowly. Keep your tension relaxed. Because mohair is fuzzy, it can be difficult to see exactly where your hook should go — working in good light and taking your time will make a huge difference.
If you drop a stitch and need to rip back, do so very carefully and slowly. Mohair’s halo means the fibers catch on each other and on your other stitches, and rushing will lead to tangles. Take it stitch by stitch.
Mark your rows as you go. With a fabric as soft and uniform as mohair hdc, it can be genuinely difficult to count rows visually. A simple tally on a sticky note next to your work will save you a lot of confusion.
Finally, enjoy the process. Crocheting with mohair is genuinely luxurious. The way the yarn moves through your fingers, the way the fabric grows and shifts in the light — it is one of those projects that feels like a pleasure from beginning to end. And when you pull it on for the first time and it fits and it is soft and it is yours, every hour you spent will feel worth it ten times over.
Autumn is waiting. Get your hook and cast on.
