Best Yarn for Blankets: A Guide for Knitters and Crocheters
Quick answer: The best yarn for blankets is a machine-washable worsted or bulky weight yarn in acrylic, cotton, or a superwash wool blend. Choose based on who the blanket is for, how it'll be used, and your budget.
Blankets are one of the most satisfying things you can knit or crochet — but they also take the most yarn. Choosing the wrong yarn means hours of work that doesn't feel right to snuggle under, pills after one wash, or runs out three-quarters through.
Here's how to pick the right yarn for your blanket the first time.
5 Questions to Ask Before You Buy
- Who is the blanket for? Baby blankets need gentle, washable yarn. A gift for an adult should be soft but durable. Your own throw? Go luxurious.
- How will it be used? A decorative throw needs drape. An everyday couch blanket needs to survive the washing machine. An outdoor blanket needs to be tough.
- What fiber do you prefer? Acrylic is budget-friendly and machine-washable. Cotton is breathable for warm climates. Wool is warmest but needs more care (unless it's superwash).
- What size are you making? A baby blanket takes 800–1,200 yards. A throw takes 2,000–3,500 yards. A queen/king takes 4,000–7,000+ yards. Size determines your budget.
- What's your yarn budget? At 3,000+ yards for a throw, even a $2/skein difference adds up fast. Plan accordingly.
Best Yarn Weights for Blankets
Worsted Weight (Category 4) — Most Versatile
The classic blanket yarn. Worsted strikes the perfect balance between speed and fabric quality. The resulting blanket has great drape, isn't too heavy, and works for year-round use. Most blanket patterns are written for worsted weight.
- Best for: all-purpose blankets, baby blankets, gifts, detailed stitch patterns
- Hook/needle: 5mm–6mm
- Yardage estimate (throw): 2,500–3,500 yards
Bulky Weight (Category 5) — Fastest Results
If you want a blanket finished in days rather than weeks, bulky yarn is your friend. The thick fabric is cozy and warm — perfect for winter throws. The tradeoff is that bulky blankets can be heavy and use more yarn by weight.
- Best for: quick projects, chunky throws, winter warmth, beginner blankets
- Hook/needle: 6.5mm–9mm
- Yardage estimate (throw): 1,500–2,500 yards
DK Weight (Category 3) — Best Drape
DK makes a lighter blanket with beautiful drape — ideal for baby blankets, summer throws, or heirloom pieces with detailed stitch work. It takes longer to complete but the fabric quality is worth it.
- Best for: baby blankets, summer throws, detailed patterns, lighter weight
- Hook/needle: 4mm–5mm
- Yardage estimate (throw): 3,500–5,000 yards
Best Fiber Types for Blankets
Acrylic — The Workhorse
For everyday blankets, acrylic is hard to beat. It's machine washable, holds color beautifully, doesn't pill as quickly as you'd expect from modern acrylics, and costs a fraction of natural fibers. When you need 3,000+ yards, the price difference really matters.
Best for: everyday throws, baby blankets, gifts (recipient doesn't need special care instructions), budget projects.
Cotton — Breathable and Year-Round
Cotton blankets are perfect for warmer climates or year-round use. The fabric is crisp, heavy, and gets softer with every wash. Cotton is also hypoallergenic — great for babies and anyone with wool sensitivities.
Heads up: cotton blankets can be heavy, especially in larger sizes. They also don't have the stretch/memory of wool or acrylic, so gauge matters more.
Superwash Wool — Luxury That Lasts
Wool is the warmest option and has a natural elasticity that makes your stitches even and your blanket springy. Superwash-treated wool can go in the washing machine, removing the biggest downside of wool blankets.
Best for: heirloom blankets, winter throws, self-gifts where quality matters most.
Acrylic-Wool Blends — Best of Both
Blends give you wool's warmth and elasticity with acrylic's washability and price point. A 75/25 or 50/50 acrylic-wool blend is arguably the sweet spot for blankets.

Smooth, mercerized cotton that gets softer with every wash. Excellent for baby blankets and summer throws. The DK weight makes a lighter blanket with beautiful drape.
How Much Yarn Do You Need for a Blanket?
This is the question everyone asks — and the answer depends on yarn weight and blanket size. Here's a general guide for worsted weight yarn:
| Blanket Size | Dimensions | Worsted (yds) | Bulky (yds) |
|---|---|---|---|
| Baby blanket | 30" × 36" | 800–1,200 | 600–900 |
| Lap/Stroller | 36" × 48" | 1,200–1,800 | 900–1,300 |
| Throw | 50" × 65" | 2,500–3,500 | 1,500–2,500 |
| Twin | 66" × 90" | 3,500–5,000 | 2,500–3,500 |
| Queen | 90" × 100" | 5,000–7,000 | 3,500–5,000 |
Pro tip: Always buy 10–15% more yarn than you think you need. Dye lots can change between production runs, and running out mid-blanket is heartbreaking. Most yarn shops (including us) have good return policies on unused skeins.

Best Yarn for Weaving Blankets
Weaving a blanket requires a different approach from knitting or crocheting one, and the yarn you choose should change accordingly. In knitting, every stitch is a loop that can give a little. On a loom, your warp threads are held under constant tension for the entire length of the project, and they abrade against each other and the reed thousands of times as you weave. A soft, fuzzy single-ply that makes a heavenly knitted throw will pill, stick to its neighbors, and snap under that treatment.
So the first thing to sort out is not fiber or color. It's which threads are doing which job!
Warp vs. Weft: The Rule That Matters Most
Warp — the threads running lengthwise, under tension. These need to be strong, smooth, and low-stretch. Test any candidate by holding a length between both hands and giving it a sharp tug. If it snaps easily, breaks with a fuzzy tear, or stretches like elastic, it does not belong in your warp.
Weft — the threads you pass side to side. These carry no tension, which is where you get to be indulgent. Softness, warmth, halo, hand-dyed color — it all lives here.
The practical upshot: a great woven blanket is very often a hard-wearing cotton or cottolin warp carrying a soft wool weft. You do not have to pick between durable and cozy - you can get both, in different directions.
Best Warp Yarns for Blankets
Mercerized and unmercerized cottons are the standard answer, and for good reason — they are strong, dimensionally stable, take dye beautifully, and are forgiving of a beginner's uneven tension. Our cotton weaving yarns are sized by the traditional two-number system (8/2, 5/2, 3/2), where the second number is the ply count and the first describes thickness — a higher first number means a finer yarn.
- Valley Yarns Valley Cotton 5/2 — the sweet spot for blankets. Fine enough to drape, sturdy enough to warp confidently.
- Valley Yarns Valley Cotton 3/2 — heavier and faster to weave, well suited to a substantial throw or a rigid heddle loom.
- Brassard 8/2 Cottolin — a cotton-linen blend. Crisp, exceptionally strong, and it softens and blooms noticeably after its first wash.
- Valley Yarns 8/2 Cotton — finer, for a lighter summer-weight blanket at a closer sett.
Best Weft Yarns for Warmth and Drape
This is where a woven blanket earns its keep. Because the weft is under no tension, most of the soft knitting yarns already covered above will work beautifully as weft — including the Berroco Vintage and Cascade 220 Superwash recommended earlier on this post.
- Wool weaving yarn — the warmest option, and it fulls handsomely when wet-finished, closing the cloth into something genuinely blanket-like.
- Valley Yarns Collingwood Rug Wool — for heavy, hard-wearing throws and camp blankets. Rugged rather than next-to-skin soft.
- Tencel and bamboo — cool, fluid, high-sheen. Choose these for a drapey summer coverlet rather than a warm winter blanket.
Sett: How Closely to Space Your Warp
Sett is measured in ends per inch (EPI), and blankets generally use a sett that's a little more open than a scarf or towel — a slightly looser cloth drapes better and feels softer over a lap. Use these as starting points to guide you:
| Yarn | Structure | Suggested Sett |
|---|---|---|
| 8/2 cotton | Plain weave | 18–20 EPI |
| 5/2 cotton | Plain weave | 12–15 EPI |
| 3/2 cotton | Plain weave | 10–12 EPI |
| Worsted weight wool | Plain weave | 8–10 EPI |
The reliable way to check any yarn, including one not listed here, is the wrap test: wind the yarn snugly around a ruler for one inch without overlapping, count the wraps, and take roughly half that number as your plain-weave sett. Then weave a sample and wet-finish it before you commit to four yards of warp.
Loom Waste: Why Weaving Needs More Yarn Than You Think
This is the step that catches people out. A woven blanket needs significantly more yarn than the finished dimensions suggest, for three reasons that compound:
- Loom waste — the warp gripped by the rods and knots that can never be woven. Budget 18–27 inches on a floor loom, and around 24 inches on a rigid heddle.
- Take-up — warp travels over and under weft rather than in a straight line, consuming roughly 10 percent of its length.
- Shrinkage — wet-finishing draws the cloth in another 5–15 percent, more with wool that you intend to full.
A working rule: Add about 25 percent to your finished length for take-up and shrinkage, then add your loom waste on top as a flat figure. For a 60-inch throw on a rigid heddle, that means warping roughly 75 inches plus 24 inches of waste — about 99 inches, or nearly three yards, to end up with five feet of blanket.
Weaving a Blanket Wider Than Your Loom
Most rigid heddle looms are narrower than a finished blanket, but that is not the obstacle it appears to be. You can weave two or three long panels at the same sett and seam them lengthwise — a centuries-old solution that shows up in Welsh and Scandinavian blankets alike. Another option is to weave all panels on a single continuous warp so the tension and beat remain consistent between them, and wet-finish before seaming, not after. Our rigid heddle looms — including the Schacht Cricket and Schacht Flip — handle panel-woven blankets well.

Tips for Your Best Blanket
- Swatch first. Yes. even for a blanket! A quick 4" × 4" swatch confirms your gauge and how the yarn feels as fabric. Just bear in mind that a large blanket will likely stretch and distort over time, especially when washed or handled.
- Buy all your yarn at once. Same dye lot = consistent color across your entire blanket. We label dye lots on every skein.
- Consider a stripe pattern. Using 2–3 colors breaks up the monotony of a large project and lets you use smaller quantities of each.
- Machine-washable matters. Unless you're making a display piece, choose yarn that can handle the washing machine. You (or the recipient) will thank yourself later.
- Don't fight the weight. If a pattern calls for bulky, don't substitute worsted — you'll change the size, drape, and yardage requirements.
Frequently Asked Questions
What is the best yarn to crochet a blanket with?
A machine-washable worsted or bulky weight acrylic or acrylic-wool blend. These give you the best combination of softness, durability, washability, and value for the large yardage blankets require.
Is acrylic or cotton better for blankets?
Acrylic is better for cozy, warm blankets — it's lighter, cheaper, and machine-dries easily. Cotton is better for summer blankets and baby items — it's breathable and hypoallergenic but heavier.
What weight yarn makes the warmest blanket?
Bulky weight (category 5) makes the warmest blanket per square inch. But a worsted weight wool or wool-blend blanket can be just as warm with a thinner, more drapey feel.
How many skeins do I need for a throw blanket?
For a standard 50" × 65" throw in worsted weight, plan on 13–18 skeins of 200-yard skeins (2,500–3,500 total yards). Check your pattern for specific requirements.
What yarn is best for a baby blanket?
A soft acrylic or cotton yarn in worsted or DK weight. Make sure it's machine washable — baby items need frequent washing. Avoid wool (potential allergies) unless you know the family is comfortable with it.
