Short answer: the best yarn for a chunky knit blanket is a spun super bulky (weight 6) natural wool, knitted on 20–25 mm needles. It's warm, breathable, holds its shape and lasts for years. With our FACES yarn (200 g / 100 m) you need 8 to 10 skeins: about 800–1,000 m and 1.6–2 kg of wool.
Which yarn type to choose
| Yarn type | Pros | Cons |
|---|---|---|
| Spun natural wool (super bulky) | Warm and breathable, full-bodied, keeps its shape, crisp stitches | Hand wash; costs more than acrylic |
| Unspun wool roving (XXL) | Very voluminous look, good for arm knitting | Very heavy, pills and felts with use; doesn't stand up well to daily use |
| Acrylic | Cheap and machine-washable | Less breathable, pills and loses loft over time |
| Polyester chenille | Very soft to the touch, washable | Stretches and stitches can work loose; not as warm as wool |
If you want a blanket you'll use on the sofa for years, spun wool is the safest bet. Our FACES is 100% Peruvian Highland wool: lofty and hard-wearing, ideal for big stitches. Why we chose Highland over merino is explained in Highland wool vs merino.
How much yarn you need for a chunky blanket
According to our FACES yarn requirement chart, a blanket takes 8–10 skeins. When planning, add one skein to your estimate: dye lots can vary and it's better to have everything from the same lot.
| Yarn | Skeins | Length | Blanket weight |
|---|---|---|---|
| FACES (super bulky, 200 g / 100 m) | 8–10 | 800–1,000 m | about 1.6–2 kg |

Which needles to use
- Size: 20–25 mm. On smaller needles the blanket turns out dense, stiff and much heavier.
- Type: circular needles with a long cable (80–120 cm). The blanket's weight rests on the cable, not on your wrists.
- Material: wood or bamboo, lighter than metal in big sizes.

Which stitch to use
- Garter stitch: the easiest, reversible and doesn't curl at the edges.
- Seed stitch: a pebbly texture, also reversible and flat.
- Stockinette: smooth on the front but it curls; add a 4–5 stitch garter border.
New to knitting? Start small: the PEBBLE HUG COWL is knitted in seed stitch with a single skein of FACES, so you practice the same stitch you'll use on the blanket. Videos for every stitch are on our Learn to knit page.
How to care for a wool blanket
Air it often: wool largely cleans itself. When it does need a wash, hand wash in lukewarm water (30 °C max) with wool wash, without rubbing or wringing. Press the water out inside a towel and dry it flat, never hanging: wet wool is heavy and would stretch out of shape.
FAQ
How long does a chunky blanket take to knit?
With super bulky yarn on 20–25 mm needles the blanket grows very fast: it's a project of a few weekends, not months.
Can I crochet it instead?
Yes, with a large hook, but the fabric is denser and uses more yarn than knitting.
Is a wool blanket itchy?
Peruvian Highland wool isn't itchy for most people, and a blanket touches your skin far less than a sweater does.
