How to Crochet a Chunky Mohair Cardigan: A Complete Step-by-Step Guide

There is something undeniably magical about a chunky mohair cardigan. The way the fibers catch the light, the cloud-like softness against your skin, and the effortless elegance it adds to any outfit make it one of the most sought-after handmade garments you can create. Whether you are a seasoned crocheter looking for your next project or an intermediate maker ready to level up your skills, crocheting your own chunky mohair cardigan is deeply satisfying and surprisingly achievable.

This guide will walk you through everything you need to know — from choosing the right yarn and tools to understanding construction, working through the pattern, and finishing your garment beautifully. By the end, you will have all the knowledge you need to create a stunning, wearable piece that looks like it came straight from a high-end boutique.

Why Chunky Mohair Is Such a Special Yarn to Work With

Before diving into the how-to, it helps to understand what makes mohair yarn so unique — and why working with chunky mohair requires a slightly different approach than standard acrylic or wool.

Mohair comes from the Angora goat and is known for its lustrous sheen, incredible softness, and that signature halo effect — the fine, wispy fibers that surround the core of the yarn and give it that dreamy, fuzzy appearance. When blended with silk (as it often is in laceweight mohair), the result is a yarn that is simultaneously lightweight and warm, delicate-looking yet surprisingly durable.

“Chunky” mohair typically refers to one of two things: either a thicker-spun mohair yarn, or — more commonly in the crochet world — mohair held alongside another yarn, such as a merino wool or alpaca blend, to create a thicker, more textured fabric. This double-stranding technique is popular because it gives you the halo and softness of mohair with the structure and body of a heavier base yarn.

Working with mohair does come with a learning curve. The halo can make it difficult to see your stitches, it does not frog (unravel) easily, and tension requires a bit of practice. But the results are absolutely worth the effort, and with the right preparation, you will find it far less intimidating than you might expect.

What You Will Need

Yarn

For a classic chunky mohair cardigan, you have a few options depending on the look you are going for.

If you want the classic halo finish that photographs beautifully, you will want to use a fine or laceweight mohair-silk blend held together with a chunky or bulky weight yarn. Something like Drops Kid-Silk or Lang Yarns Lace held double with a worsted or chunky merino is a popular combination. Plan for approximately 600 to 900 yards of the base yarn and 400 to 600 yards of the mohair-silk, depending on your size.

If you prefer a simpler approach, look for a purpose-spun chunky mohair blend yarn. These exist in boutique and hand-dye markets and are designed to be used as a single strand for the intended gauge.

Hooks

Chunky mohair cardigans are typically worked on larger hooks than you might expect. A 6mm to 10mm hook is common. The larger the hook relative to the yarn weight, the more open and drapey the fabric will be — which is often the desired effect for this type of garment. If you are double-stranding, start with a 7mm or 8mm hook and swatch to check your gauge.

Other Supplies

You will need stitch markers (locking markers work best for mohair), a blunt tapestry needle for seaming and weaving in ends, measuring tape, and scissors. If your pattern calls for buttons, choose ones that are large enough not to slip through the stitches accidentally — 20mm to 25mm buttons work well for chunky fabric.

Understanding Gauge and Why It Matters More With Mohair

With any crochet garment, gauge is everything. With mohair, it is even more important because the halo can visually disguise your true stitch size, making it harder to assess accuracy by eye alone.

To check gauge, crochet a swatch of at least 6 inches by 6 inches using the hook and yarn you plan to use for your project. Block the swatch (yes, even before starting the garment) and then measure the center 4 inches. Compare your stitch and row count to the pattern’s stated gauge.

A typical chunky mohair cardigan worked in half double crochet or extended single crochet might have a gauge of around 12 to 14 stitches and 9 to 11 rows per 4 inches, but this varies considerably by pattern and desired drape. If your swatch has too many stitches, go up a hook size. If it has too few, go down.

Do not skip the swatch. A difference of even half a stitch per inch can result in a cardigan that is several inches too large or too small after all your hard work.

Choosing Your Construction Method

Chunky mohair cardigans can be constructed in several different ways, each with its own advantages.

Top-Down Construction

Top-down cardigans are worked from the neckline downward, with increases made at the raglan or yoke to shape the shoulders and body simultaneously. This method allows you to try the garment on as you go, making adjustments to length and ease in real time. It is forgiving for beginners and produces minimal seaming.

Bottom-Up Construction

In bottom-up construction, you work each piece separately — back panel, two front panels, and sleeves — and then seam them together. Some crocheters prefer this method because working flat pieces can feel easier to manage, especially with a sticky yarn like mohair.

Sideways or Granny-Square Construction

Some modern chunky cardigan patterns are worked sideways (from cuff to cuff) or built from modular squares. These are less common but create interesting texture and can be a fun departure from traditional construction.

For this guide, we will focus on a top-down construction, as it is the most beginner-friendly approach for a first mohair cardigan.

The Pattern: A Simple Top-Down Chunky Mohair Cardigan

This pattern is written for an adult size medium (bust 38–40 inches) with notes for adjustments. All abbreviations are standard US crochet terminology.

Abbreviations

ch — chain, sc — single crochet, hdc — half double crochet, dc — double crochet, st(s) — stitch(es), sp — space, rep — repeat, pm — place marker, sm — slip marker, RS — right side, WS — wrong side

Stitch Pattern

This cardigan is worked in a simple extended half double crochet (ehdc), which creates a slightly taller and softer stitch than standard hdc and drapes beautifully in mohair. To work an ehdc: insert your hook, yarn over, pull up a loop, yarn over, pull through the first loop only (this is the “extended” part), yarn over, pull through all three loops on the hook.

Starting the Yoke

Begin with a foundation chain of 60 chains (adjust for size: 52 chains for XS/S, 60 for M/L, 68 for XL/2XL).

Row 1 (RS): Work 1 ehdc in the 3rd chain from hook, then in each chain across. Turn. (58 stitches for M/L)

Row 2: Ch 2 (does not count as a stitch throughout), ehdc in each st across. Turn.

Now you will set up your raglan increase points. Place stitch markers at the following positions to divide your yoke into sections: 10 stitches for the right front, 1 stitch for the right raglan, 16 stitches for the back, 1 stitch for the left raglan, 16 stitches for the back, 1 stitch for the right raglan — wait, let us be more precise.

Raglan Setup Row

Divide your 58 stitches as follows: 10 sts right front, 1 raglan st (pm), 16 sts right sleeve, 1 raglan st (pm), 20 sts back, 1 raglan st (pm), 16 sts left sleeve, 1 raglan st (pm), 10 sts left front.

Raglan Increase Row (worked every right-side row):

Ch 2, work ehdc across to 1 st before first marker, work 3 ehdc in that stitch (increase made), sm, continue to 1 st before next marker, work 3 ehdc in that stitch, sm, repeat across all 4 raglan points, ehdc to end. Turn.

Wrong Side Rows: Ch 2, ehdc across without increasing. Turn.

Repeat these two rows until you have worked 14 increase rows total (you will have increased 8 stitches per RS row, adding 112 stitches to your total, giving you approximately 170 stitches).

At this point your yoke should measure approximately 7 to 8 inches deep from the foundation chain. Try it on — the yoke should sit comfortably on your shoulders with the raglan lines falling at or just past your shoulder seam.

Separating the Sleeves

On the next RS row, work across to the first raglan marker. Chain 4 (this forms the underarm). Skip all sleeve stitches to the next raglan marker. Work across the back stitches. Chain 4 for the second underarm. Skip the second set of sleeve stitches. Work to the end of the left front.

On the next row, work across, treating each 4-chain underarm as 4 stitches.

Your body stitch count should now be approximately 100 to 110 stitches across.

Working the Body

Continue working in rows (back and forth), working ehdc across every row until the body measures your desired length from the underarm. For a classic oversized cardigan, aim for 14 to 16 inches of body length below the underarm, or adjust to your preference.

If you want to add subtle waist shaping, you can work 2 to 3 decrease rows in the center of the body section and then increase back out, but many chunky mohair cardigans are intentionally boxy and look wonderful without any shaping.

The Hem

For a clean, relaxed hem, work 2 rows of standard single crochet across the bottom of the body. This creates a slightly firmer edge that lies flat and does not curl.

Working the Sleeves

Return to your held sleeve stitches. Reattach yarn at the underarm chain. Pick up and work across all sleeve stitches plus the 4 underarm chains, joining in the round with a slip stitch. (Approximately 52 to 60 stitches depending on your size.)

Work in continuous rounds of ehdc for approximately 12 inches (or until sleeve is 2 to 3 inches shorter than your desired length). Then work decrease rounds: decrease approximately 4 stitches evenly across every 4th round until the cuff is approximately 36 to 40 stitches.

Work 2 rounds of single crochet at the cuff edge.

The Front Bands and Neckline

The front bands are one of the most important finishing details on a cardigan. Work them carefully and they will make the entire garment look polished and intentional.

With RS facing, attach yarn at the bottom right front corner. Work single crochet evenly up the right front edge, around the back neckline, and down the left front edge. A good rule of thumb is to work approximately 2 sc for every 3 row ends along the front edges, and 1 sc in every stitch along the neckline.

Work 3 rows of sc total. On the second row of the left front band (for a woman’s cardigan), work evenly spaced buttonholes: ch 2, skip 2 sts for each buttonhole. Space them evenly — typically 5 to 7 buttons depending on the length of your cardigan.

On the third row, fill in each buttonhole gap with 2 sc.

Blocking Your Mohair Cardigan

Blocking is non-negotiable with a mohair cardigan. The process relaxes the fibers, evens out the stitches, and — most importantly with mohair — opens up the halo to give you that gorgeous, ethereal appearance.

Fill a clean basin or bathtub with lukewarm water and a small amount of wool wash. Gently submerge your cardigan and allow it to soak for 20 to 30 minutes without agitating. Do not wring or twist.

Carefully lift the garment (it will be heavy when wet) and gently press out excess water. Lay it flat on blocking mats or clean towels and smooth it into shape, pinning the edges if needed. Measure as you go to ensure the dimensions match your intended size.

Allow it to dry completely — this may take 24 to 48 hours. Resist the temptation to speed up the process with a hair dryer or heat, as this can damage the fibers.

Once dry, the halo will have bloomed beautifully. You will notice the stitches are less visible and the fabric has a much softer, more uniform appearance.

Tips for Working Successfully With Mohair

Working with mohair becomes much easier once you know a few key strategies.

Work in good lighting. The halo can obscure your stitch definition in dim conditions, making it hard to insert your hook correctly. A daylight bulb or natural light makes a significant difference.

Work slowly and mindfully. Mohair does not forgive rushed movements. Take your time inserting your hook into the correct stitch, and you will find your rhythm quickly.

Avoid frogging if at all possible. Unlike standard yarn, mohair fibers cling to each other and can be very difficult to unravel once worked. This is why swatching and careful gauge checking are so important before you begin. If you do need to undo a section, do it stitch by stitch rather than pulling the yarn out all at once.

Use a contrasting stitch marker in a color that stands out against your yarn. Since the halo obscures stitch definition, clear markers placed at key points help you count correctly without counting every stitch each row.

Store your working yarn in a zip-lock bag with a small hole cut for the working end. This keeps the halo from tangling with itself or collecting lint and dust while you work.

Styling Your Finished Cardigan

One of the best things about a chunky mohair cardigan is its versatility. The same garment can read casual or elevated depending on how you style it.

For a relaxed everyday look, wear it unbuttoned over a simple white tee and high-waisted jeans with ankle boots. For something more polished, button it fully and wear it as a sweater over trousers and heels. In cooler months, layer it over a turtleneck or thin mock-neck for warmth without bulk.

Neutral tones — cream, camel, oatmeal, dusty rose, and warm grey — are perennially popular for mohair cardigans because they work with almost everything in your wardrobe. That said, a chunky mohair cardigan in a deep jewel tone or rich earthy color makes an incredible statement piece.

Caring for Your Handmade Mohair Cardigan

To keep your cardigan looking its best for years, hand wash it in cold or lukewarm water with a gentle wool wash, following the same process as blocking. Reshape while damp and dry flat. Never hang a wet mohair garment, as the weight of the wet fiber can stretch it out of shape.

Store it folded rather than on a hanger. Hang storage can cause the shoulders to stretch over time. A cedar block or lavender sachet stored nearby will help protect the natural fibers.

With proper care, a handmade chunky mohair cardigan can last for many years — and the more you wear and wash it, the softer it becomes.

Final Thoughts

Crocheting a chunky mohair cardigan is one of those projects that truly delivers on its promise. The process of working with such a luxurious yarn, watching the halo bloom with every row, and seeing the garment take shape is a genuinely enjoyable experience — and the finished object is something you will reach for again and again.

Give yourself grace with the learning curve of mohair. Swatch carefully, work in good light, and take it one row at a time. The technique becomes second nature quickly, and the reward at the end is a wearable piece of handmade art that is uniquely yours.

Now gather your yarn, grab your hook, and cast on. Your dream cardigan is closer than you think.
