Best Yarn for Crochet Garments
A knitted sweater needs memory. A crocheted one needs the opposite, and picking it like a knitting yarn is why so many come out looking like armor.

The short answer
Pick for drape, and pick a lighter weight than you would knit with. Crochet fabric is thicker, denser and heavier than knitted fabric made from the same yarn, so a yarn with springback produces a garment that stands away from the body. DK in rayon, a cotton-bamboo blend or a soft acrylic will hang; mercerized cotton and firm wool will not. Go up a hook size from the ball band, and swatch a piece large enough to hang under its own weight.

Lion Brand Truboo
Lion Brand · Best for a crocheted top or cardigan that hangs
Rayon from bamboo, in DK - the drapiest widely stocked plant yarn, and the one people mean when they say bamboo yarn.
- Fiber
- 100% rayon from bamboo
- Weight
- 3 Light / DK
- Skein
- 3.5oz / 100g, 241yd / 220m
- Gauge
- 23 sts x 32 rows on US 6 (4mm)
- Hook
- G-6 (4mm), 18 sc x 20 rows
- Care
- Machine wash, lay flat to dry
Who it suits
Anyone making their first crocheted garment who does not want it to stand away from the body.
Why it is here
100% rayon from bamboo, category 3 light / DK, 241yd per 100g skein, with a published crochet gauge of 18 single crochet and 20 rows over 4in on a G-6 (4mm) hook. Rayon has almost no elasticity and a high specific weight, which is a liability in a knitted sweater and exactly what a crocheted one needs - the fabric falls instead of standing.
What you give up
It is slippery, splits easily and has no recovery at all, so ribbed cuffs and hems will not pull in. Wet rayon is also weak, which makes blocking a careful job rather than a rough one.

Cascade 220 Superwash Merino
Cascade Yarns · Best for a crocheted cardigan for real winters
Machine-washable merino at 220 yards to the 100g skein - the standard answer when a sweater pattern says worsted and you want to be able to wash it.
- Fiber
- 100% superwash merino wool
- Skein
- 3.5oz / 100g, 220yd / 200m
- Gauge
- 20 sts x 28 rows in stockinette on US 7
- Weight class
- DK to light worsted
- Care
- Superwash treated - machine washable
Who it suits
Anyone who wants warmth and is willing to swatch for the drape rather than get it free from the fiber.
Why it is here
100% superwash merino, 220yd to a 100g skein, classed DK to light worsted and knit at 20 sts x 28 rows on a US 7. Superwash merino is softer and less springy than untreated wool, which in crochet is an advantage - and the yardage is enough that a garment does not need a mountain of skeins.
What you give up
Wool has memory, so a dense crochet stitch in it will stand away from the body unless you go up a hook size or use an open stitch. It is also the most expensive yarn on this page by a clear margin.

Lion Brand Coboo
Lion Brand · Best for summer garments
Cotton and bamboo in roughly equal parts - the blend that keeps bamboo's drape and adds enough cotton to hold a stitch.
- Fiber
- 51% cotton, 49% rayon from bamboo
- Weight
- 3 Light / DK
- Skein
- 3.5oz / 100g, 232yd / 212m
- Gauge
- 23 sts x 32 rows on US 6 (4mm)
- Hook
- G-6 (4mm), 18 sc x 20 rows
- Care
- Machine wash, machine dry
Who it suits
Anyone crocheting a warm-weather top who has been defeated by pure cotton.
Why it is here
51% cotton and 49% rayon from bamboo, category 3 light / DK, 232yd per 100g, published at 18 single crochet and 20 rows on a G-6 (4mm) hook. The blend is the point: bamboo alone is too slippery to hold a crisp stitch, cotton alone is too stiff to drape, and half of each behaves.
What you give up
Still inelastic, so it stretches with wear and does not come back. Machine washable and machine dryable per the band, which is more than most drapey yarns manage.

Caron Simply Soft
Caron · Best for a first garment you are not precious about
A softer, shinier acrylic worsted with noticeable drape - which is exactly why it is a poor choice for anything that needs to hold a shape.
- Fiber
- 100% acrylic
- Weight
- 4 Medium / worsted
- Skein
- 6oz / 170g, 315yd / 288m
- Gauge
- 18 sts x 24 rows on 5mm (US 8)
- Hook
- 5mm (US H/8), 13 sc x 14 rows
- Care
- Machine wash cool, dry flat, no bleach
Who it suits
Anyone testing a garment pattern before committing to expensive yarn.
Why it is here
100% acrylic, category 4 medium, 315yd per 170g skein, 13 single crochet and 14 rows over 4in on a 5mm hook. It is softer and shinier than most acrylics with noticeably more drape - which makes it a poor choice for anything that needs to hold a shape, and exactly the right choice for something that needs to hang.
What you give up
The sheen reads as synthetic in daylight, and at worsted weight the fabric is heavier than the DK options here. It also splits, so pair it with a tapered hook.

Lion Brand 24/7 Cotton
Lion Brand · Best for bags, baskets and amigurumi
Mercerized cotton with a sheen and a stiff hand. Stitch definition is the best on this page, which is why amigurumi people keep buying it.
- Fiber
- 100% mercerized cotton
- Weight
- Worsted
- Skein
- 3.5oz / 100g, 186yd / 170m
- Gauge
- 19 sts x 26 rows on 5mm (US 8)
- Hook
- 5.5mm (US I/9), 16 sc x 18 rows
- Care
- Machine wash, water not above 105F; medium heat dryer
Who it suits
Not garment makers. For a market bag or a stiff amigurumi it is genuinely excellent.
Why it is here
100% mercerized cotton, worsted, 186yd per 100g, published at 16 single crochet and 18 rows on a 5.5mm hook. Mercerizing treats the fiber under tension, which is what produces the sheen, the strength and the stiff hand.
What you give up
Stiffness and weight are the two things a crochet garment can least afford. A mercerized cotton sweater stands away from the body, weighs a great deal, and stretches permanently at the shoulders under its own mass.
Specifications from Lion Brand product page. We have not handled this item - see how we pick.
Why crochet garments are a separate problem
A crochet stitch encloses more yarn and stands taller than a knit stitch. The same yarn worked in single crochet makes a fabric that is measurably thicker and heavier than the same yarn in stockinette, and considerably less elastic.
- Denser. More yarn per square inch means more weight hanging off the shoulders.
- Stiffer. Each stitch is anchored on more sides, so the fabric bends less readily.
- Less elastic. A knitted fabric stretches in both directions; a crocheted one mostly does not.
- Slower to grow, faster per row, which changes nothing about the fabric but everything about the ball count.
That is why best yarn for a sweater reaches a different answer. It is written around knitted fabric, where springback is the virtue that keeps a garment in shape. In crochet, springback is what makes the garment stand up on its own.
Weight, and why DK usually wins
Worsted is the default crochet weight for almost everything else on this site, and for garments it is usually one step too heavy.
| Weight | Fabric | Verdict for garments |
|---|---|---|
| Fingering | Fine, light, very slow | Beautiful, and a long project |
| Sport / DK | Light enough to hang | The sweet spot |
| Worsted | Warm, heavy, structural | Works for cardigans and outerwear |
| Bulky and up | Stiff and very heavy | Not a garment fabric |
The rule of thumb that works: if a knitting pattern for the same garment would use worsted, crochet it in DK. DK vs worsted yarn sets out the gap between the two.
Fiber, ranked for this job
- Rayon and bamboo. Maximum drape, no memory. The best drape available and the hardest to work with.
- Cotton-bamboo blends. Most of the drape, easier to handle, machine washable.
- Soft acrylics. Surprisingly good drape for the money, and the cheapest way to test a pattern.
- Superwash merino. Softer and less springy than untreated wool, so it behaves better in crochet than wool usually does.
- Untreated wool. Memory and bloom - excellent knitted, stiff crocheted.
- Mercerized cotton. Stiff and heavy. Superb for bags, wrong for bodies.
- Chenille and blanket yarn. Not garment fabric at any weight.
Stitch choice does as much as yarn choice
You can rescue a slightly stiff yarn with an open stitch, and you can ruin a drapey one with a dense stitch. The fabric is the pair working together.
- Single crochet is the densest and stiffest common stitch. Beautiful for toys, heavy for garments.
- Half double and double crochet are taller and more open, and both drape better.
- Mesh and lace stitches drape best of all, and use far less yarn.
- Going up a hook size loosens any of them - for garments, going one size above the band is normal rather than a cheat.
- Ribbing does not work in most yarns here, because none of them has enough recovery. Design around it rather than fighting it.
Best crochet hooks for garments covers the tool side, and best crochet hook for DK yarn the size.
Yardage, and the shoulder problem
Crochet uses roughly a third more yarn than knitting for the same area, and all of it hangs from the same seams. Two practical consequences follow.
- Buy more than a knitting pattern would suggest for the same garment, and buy it all at once so the dye lots match.
- Expect the finished piece to be heavy, which is a fit problem rather than a comfort one.
- Reinforce the shoulders, because an inelastic fabric carrying that weight will stretch there first.
- Block on the flat, never on a hanger. A wet crochet garment hung up will lengthen and stay lengthened.
- Store folded for the same reason.
How we picked
Every yarn here is one we already list, chosen on its published fiber content, weight class, yardage and stated crochet gauge where the manufacturer gives one. The ranking is on drape, because that is the property a crocheted garment lives or dies by. Nothing here is a testing claim - the sources are the manufacturers' own specifications, listed below.
What we would buy
- Maximum drape: rayon from bamboo in DK.
- Drape plus washability: the cotton-bamboo blend.
- Warmth: superwash merino.
- Testing a pattern cheaply: soft acrylic.
- Not for a garment: mercerized cotton.
Questions people actually ask
What yarn is best for crochet garments?
A DK-weight yarn with drape - rayon from bamboo, a cotton-bamboo blend, or a soft acrylic. Crochet fabric is denser and heavier than knitted fabric at the same yarn, so anything with springback makes a garment that stands away from the body.
Why do my crochet sweaters look stiff?
Usually two things at once: a yarn with memory, such as untreated wool or mercerized cotton, and a dense stitch such as single crochet at the ball band's hook size. Switch to a drapier fiber, a taller stitch, and a hook one size larger.
Should I crochet a garment in DK or worsted?
DK, in most cases. The usual rule is that if you would knit the garment in worsted, crochet it in DK - crochet fabric at the same yarn comes out thicker and heavier than the knitted equivalent.
Can I use cotton yarn for a crochet sweater?
Unmercerized cotton or a cotton blend, yes. Mercerized cotton is stiff and heavy, and a garment made from it stands away from the body and stretches permanently at the shoulders under its own weight.
Does crochet use more yarn than knitting?
Yes, roughly a third more for the same area, because a crochet stitch encloses more yarn. Buy accordingly, and buy the whole quantity at once so the dye lots match.
