Best Yarn for Granny Squares
One square is easy. Fifty squares in twelve colors, joined and washed for a decade, is a yarn problem.

The short answer
Use a worsted weight acrylic with anti-pilling spin, or a budget acrylic if you need many colors. A granny square blanket is dozens of squares that get joined, washed and sat on, so pilling and color availability matter more than softness. Avoid chenille - it fills in the chain spaces that make a granny square look like one.

Lion Brand Basic Stitch Anti-Pilling
Lion Brand · Best for a blanket meant to survive a decade
An acrylic worsted sold specifically on its pilling behavior, which is the one complaint that ends most acrylic garments.
- Fiber
- 100% acrylic
- Weight
- 4 Medium / worsted
- Skein
- 3.5oz / 100g, 185yd
- Gauge
- 18 sts x 26 rows on US 8 (5mm)
- Hook
- H-8 (5mm), 16 sc x 18 rows
- Care
- Machine wash, machine dry
Who it suits
Anyone making a blanket that will be used rather than displayed.
Why it is here
100% acrylic, worsted weight, 185yd per 100g, 18 sts x 26 rows on 5mm. A granny blanket has hundreds of exposed stitch edges and gets sat on, washed and dragged around - ordinary acrylic pills at exactly those contact points, and this is spun specifically to resist it.
What you give up
The color range is smaller than the big budget acrylics, which matters when a design calls for twelve shades. It also costs more per yard than Super Saver.

Red Heart Super Saver
Red Heart · Best for a twelve-color scrap-look blanket
The 7oz workhorse acrylic. Coarser than the softer acrylics here, and the cheapest yardage on the shelf by a distance.
- Fiber
- 100% acrylic
- Weight
- 4 Medium / worsted
- Skein
- 7oz / 198g, 364yd / 333m (no-dye-lot solids)
- Gauge
- 17 sts x 23 rows on 5mm (US 8)
- Hook
- 5.5mm (US I/9), 12 sc x 15 rows
- Care
- Machine wash warm gentle, tumble dry low, no bleach
Who it suits
Anyone whose design needs many colors, and anyone making a blanket on a budget.
Why it is here
100% acrylic, worsted weight, 364yd per 198g - by far the most yardage per ball on this page - with no-dye-lot solids, which means you can buy a replacement ball months later and it will match.
What you give up
It is stiff and slightly scratchy off the ball, and it pills. It softens noticeably after two or three washes, which is worth knowing before you judge it.

Caron Simply Soft
Caron · Best for a blanket that hangs rather than stands
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 who has made a stiff granny blanket before and wants a softer one.
Why it is here
100% acrylic, worsted weight, 315yd per 170g. A light twist and a slight sheen give it drape that is unusual for a worsted acrylic, and a motif blanket is one of the few places where drape genuinely improves the result.
What you give up
The loose spin that makes it soft is also what makes it split on the hook and pill in use. It is a comfort-first choice rather than a durability-first one.

Lion Brand 24/7 Cotton
Lion Brand · Best for squares where the pattern is the point
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
Anyone crocheting an intricate motif rather than a classic three-round granny.
Why it is here
100% mercerized cotton, worsted weight, 186yd per 100g. Cotton has no halo, so the negative space that defines a granny square stays sharp - and mercerized cotton holds bright colors without fading.
What you give up
A cotton blanket at full size is genuinely heavy, and cotton has no give, so joining squares takes more force. Better for a baby blanket or a throw than a bedspread.

Bernat Blanket
Bernat · Best for plain, fast blankets in one piece
Polyester chenille at 108 yards to a 150g ball. Fast, warm, machine washable, and it will shed and worm if the tension is loose.
- Fiber
- 100% polyester (chenille)
- Weight
- 6 Super Bulky
- Ball
- 5.3oz / 150g, 108yd / 98m
- Gauge
- 8 sts x 13 rows on 8mm (US 11)
- Hook
- 8mm (US L/11), 7 sc x 8 rows
- Care
- Machine wash delicate, tumble dry gentle
Who it suits
Not motif crocheters. It is a fine yarn for a plain, quick throw.
Why it is here
100% polyester chenille, super bulky (CYC 6), 108yd per 150g ball, worked at 7 sc x 8 rows on 8mm.
What you give up
A granny square is defined by chain spaces - deliberate holes between clusters. The pile on a chenille yarn fills those holes in, so the finished square reads as a fuzzy blob. It also sheds at every joined edge.

What is actually different about motif work
A granny square blanket is not one big project. It is fifty small ones, joined, and that changes which yarn properties matter.
- You need many colors from one range. Different brands are not the same weight even when the label says worsted, so mixing them makes squares that do not match in size.
- Every square has ends. Fifty squares in four colors is four hundred ends. See how to weave in ends.
- Every square edge gets handled. Joining means working into the outside round of every square, twice - once when you make it and once when you join it.
- The holes are the design. Chain spaces between clusters are what makes it read as a granny square rather than as fabric.
Color, and the dye lot problem inverted
Normally the advice is to buy all your yarn in one dye lot. On a motif blanket, the far bigger risk is running out of one color halfway through and finding the shade discontinued.
This is why the big budget acrylics dominate motif crochet despite not being the nicest yarns. Red Heart Super Saver solids are sold as no-dye-lot, meaning any ball of that shade matches any other. On a project that takes six months, that is worth more than softness.
Pilling is what ends a granny blanket
Not wear, not fading. A motif blanket has an enormous amount of exposed stitch edge relative to its area, and every join is a raised ridge that takes friction first.
Ordinary acrylic pills because short fibers migrate to the surface under rubbing. An anti-pilling spin uses a construction that resists that migration, and the difference does not show for twenty washes - which is exactly when a blanket starts looking tired. Our why yarn pills page covers the mechanism.
Weight consistency matters more than you would think
If your squares come out different sizes, joining them is miserable and the finished blanket will not lie flat.
Two things cause this. The first is mixing brands - two yarns can both be labeled worsted, category 4 in the Craft Yarn Council system, and still differ enough in thickness to produce squares half an inch apart. The second is tension drift over a long project, which a gauge check against your first square will catch.
The practical rule: pick one yarn line and buy every color in it. Do not mix a Lion Brand worsted with a Red Heart worsted in the same blanket.
How many squares, and how much yarn
| Blanket | Finished size | 6in squares | Worsted yarn |
|---|---|---|---|
| Baby blanket | 30 x 36in | 30 | 700-900yd |
| Lap throw | 36 x 48in | 48 | 1,100-1,400yd |
| Twin | 60 x 84in | 140 | 3,200-4,000yd |
| Queen | 84 x 90in | 210 | 4,800-6,000yd |
Those figures include the joining and the border, which people routinely forget - the join alone is commonly ten percent of the total. The full arithmetic method is on how much yarn do I need.
Joining, briefly
- Join-as-you-go attaches each square during its final round. No sewing, far fewer ends, and the join is part of the design.
- Slip stitch join makes a visible ridge on the front. Sturdy, and deliberately decorative.
- Whip stitch with a tapestry needle is the flattest and least visible. It needs a blunt bent-tip needle and a lot of patience.
- Single crochet join is fast and bulky. Fine on a heavy blanket, too thick on a baby one.
What we would buy
- A blanket to last: Basic Stitch Anti-Pilling in as many colors as the design needs.
- Many colors, low cost: Red Heart Super Saver, and buy the joining color twice over.
- Softness first: Caron Simply Soft.
- Crisp motifs: Lion Brand 24/7 Cotton, for a baby blanket rather than a bedspread.
- For the four hundred ends: bent-tip tapestry needles. This is not optional on a motif blanket.
Questions people actually ask
What is the best yarn for granny squares?
Worsted weight acrylic with an anti-pilling spin. Motif blankets have a lot of exposed stitch edge and get handled constantly, so pilling resistance and a wide color range matter more than softness.
How much yarn do I need for a granny square blanket?
About 700 to 900 yards of worsted for a baby blanket, 1,100 to 1,400 for a lap throw, and 3,200 to 4,000 for a twin. Those figures include joining and border, which together are commonly ten percent of the total.
Can you mix yarn brands in a granny square blanket?
Not comfortably. Two yarns can both be labeled worsted weight and still differ enough in thickness to produce squares half an inch apart, which makes joining miserable and stops the blanket lying flat.
Why do my granny squares come out different sizes?
Either you mixed yarn lines, or your tension drifted over a long project. Check a new square against your first one every ten squares, the same way you would check gauge.
Is chenille yarn good for granny squares?
No. A granny square is defined by the chain spaces between clusters, and chenille's pile fills those holes in - so the square reads as a fuzzy blob. It also sheds at every joined edge.
