Does Crochet Shrink When Washed?
Worried that washing your beloved handmade crochet items might ruin them? You’re not alone – many crocheters dread the laundry day for fear of shrinkage or distortion. In this article, we’ll explain what causes crochet to shrink and how to avoid it, covering fiber differences, stitch factors, and gentle care tips. By the end, you’ll know how to safely wash and dry your favorite projects (blankets, garments or gifts) with confidence that they’ll hold their shape and beauty.
What Causes Shrinkage in Crochet?
- Fiber Content: Different yarn materials respond differently to water and heat. Natural fibers like wool and cotton tend to relax and contract in the wash. Wool’s tiny scales can hook together (felting) under heat, causing heavy shrinkage, while cotton fibers simply tighten up a bit as they dry. In contrast, synthetic yarns like acrylic are much more stable and hold their shape well – just avoid extreme heat on any yarn.
- Stitch Density & Tension: How you crochet also matters. Very tight, dense stitches (like single crochets or intricate textured patterns) pack the yarn closely and can contract more when washed. Looser, open stitches (like lace or shells) often allow water to pass through and may dry with less dramatic change. Similarly, a project worked at a very tight gauge will spring into a slightly smaller size after washing, whereas a very loose or drapey project might just hang or stretch out a little.
- Washing & Drying Conditions: The way you wash has a big impact. Using hot water, harsh detergents, or a vigorous machine cycle can make even normally stable fibers shrink. Likewise, tumble-drying on high heat will almost always shrink or distort many yarns. Gentle, cold-water washing and flat drying are key to minimizing shrinkage. Even yarn labels often warn against heat: following their instructions (for example, “machine wash cold, lay flat to dry”) is a proven way to avoid surprises.
Which Crochet Yarns Shrink More?
When comparing yarns, some fibers are more shrink-prone than others. Here’s a quick look at the main types:
Cotton
Cotton yarn (especially untreated cotton) tends to shrink a bit when first washed, especially if washed or dried with heat. Many crocheters report that a 100% cotton project may shrink a few percent after a hot wash or tumble dry. Cotton is heavy when wet and its natural tension relaxes, so it can shrink or distort slightly. To be safe, always wash cotton items in cool water and reshape them as they dry (lay them flat and gently stretch them back to size). Mercerized cotton (cotton treated for strength and sheen) generally shrinks less but still benefits from gentle care.
Wool
Wool yarns (unless labeled “superwash”) shrink the most when exposed to heat. Non-superwash wool will quickly felt and shrink if washed in hot water or put in a hot dryer – what was a cozy garment can become a tiny, stiff piece if you’re not careful. Superwash wool (treated to be machine-washable) is much safer, usually shrinking only a little (if at all) on cold, gentle washes. In any case, assume “wool = hand wash only”: use cold water, a gentle soak, and never tumble-dry wool items. Always lay wool flat to dry and reshape them gently to their original size.
Acrylic
Acrylic yarns are the least likely to shrink in crochet. These synthetic fibers hold their shape well through washes, which is why acrylic is popular for blankets and kids’ projects. You can usually machine-wash acrylic on a gentle, cold cycle without worry. The one caution is heat: a hot dryer can soften or even melt acrylic, so air-drying or a low-heat tumble is best. In summary, acrylic is easy-care, but still avoid extreme heat on it.
Blends
Blended yarns behave according to their components. For example, a cotton-acrylic blend will act more like cotton (wash cold, lay flat), while a wool-acrylic blend will need wool-like care (gentle wash, no heat). A common rule is to treat any blend by its most delicate fiber. If one part of the yarn label says “hand wash only,” do that for the whole item. Many modern blends are made to minimize shrinkage, but it’s always safest to use the care method of the yarn’s weakest fiber.
Here’s a handy comparison of these fibers and their shrinkage tendencies:
| Fiber Type | Likely Shrinkage | Care Tips |
|---|---|---|
| 100% Acrylic | Very Low | Cold machine wash; lay flat or low-heat |
| 100% Cotton (raw) | Moderate (~3–10%) | Wash cold; reshape and dry flat; avoid heat |
| Mercerized Cotton | Low-Moderate | Gentle machine wash; dry flat |
| Wool (non-superwash) | Very High (felting) | Hand wash cold; no tumble dry; flat dry |
| Wool (superwash) | Low | Machine wash gentle cold; lay flat to dry |
| Cotton-acrylic blends | Low-Moderate | Treat like cotton: cold wash, flat dry |
| Wool-acrylic blends | Moderate | Treat like wool: gentle wash, flat dry |
How to Prevent Crochet from Shrinking
To keep your crochet pieces at the right size, follow these best practices:
- Pre-Wash Your Yarn: For yarns that concern you (especially cotton or wool), consider pre-washing the skein or making a small swatch and washing it. This “pre-shrinks” the yarn so you won’t get surprises. Some yarn labels even recommend washing the yarn before starting a project.
- Swatch and Test: Always crochet a gauge swatch and wash it the way you plan to wash the finished item. Measure it before and after washing. If your swatch changes size, adjust your hook size or tension before you work the whole project. For garments, wash and dry the swatch flat to see the final size, then match your pattern to that gauge.
- Block After Crochet: After completing your piece (and after it’s clean), block it. Wet-blocking or steam-blocking your piece will set its final dimensions. Pin or shape the damp item on a flat surface to the size it should be, then let it dry fully. Blocking helps restore shrunk edges and gives your project a polished look.
- Wash & Dry Gently: Use a mild detergent and cold or lukewarm water. Hand-washing is safest, but if you use a machine, choose the gentle/delicate cycle. Always put your crochet item in a mesh bag or pillowcase to protect it. After washing, avoid wringing: gently squeeze out water or roll in a towel. Dry flat on a towel, reshaping as it dries. If using a dryer, use the lowest heat setting and remove the item while it’s still slightly damp to finish drying flat. In short, minimize agitation and heat to prevent shrinkage.

Why Some Crochet Projects Shrink More Than Others
Even with the same yarn, different projects can change differently after washing:
- Small vs. Large: Smaller items like coasters, hats, or stuffed toys often show more shrinkage (percentage-wise) than large blankets or sweaters. A tiny cotton coaster might shrink half an inch and feel significantly smaller, whereas that same shrinkage on a big blanket is hardly noticeable. Also, small items are often made with dense stitches and may stiffen up. Larger projects (like garments or afghans) might stretch out a bit when worn, making minor shrinkage less obvious.
- Stitch Patterns (Dense vs. Open): Very dense, textured stitches (think popcorn, cables, or multiple single crochets side by side) use a lot of fiber and can lock up, shrinking slightly. Open, lacy stitches (like chains, double crochet shells, or granny squares) let water through and tend to relax with blocking. For example, a tightly crocheted scarf may end up a bit shorter after washing, while a lacy shawl will likely just have its drape restored. Keep your stitch pattern in mind when anticipating any changes.
Best Yarns for Shrink-Free Crochet Projects
If you want to play it safe, here are some yarn choices favored by crochet fans for low shrinkage:
- 100% Acrylic: The go-to for easy-care items. Acrylic yarns (like Red Heart Super Saver, Caron Simply Soft, or Lion Brand Vanna’s Choice) are widely loved because they can usually be machine washed and dried with no noticeable shrinkage. They hold stitches well, though they can stretch slightly when wet.
- Superwash Wool: For garments and warm items, superwash merino or wool blends (like a treated merino or a wool-nylon blend) provide that cozy wool feel without the felting risk. These can often be washed in a machine gently. Brands like Patons Superwash or some Malabrigo (superwash lines) give wool comfort with machine-wash convenience.
- Cotton Blends: If you love cotton’s feel but want shrink control, look for cotton blends. Mercerized cotton (for example, a mercerized dishcloth cotton) shrinks less than raw cotton. Cotton-acrylic or cotton-bamboo blends combine cotton’s absorbency with acrylic’s stability. These are great for dishcloths, summer tops, or durable accessories.
- Polyester/Nylon Blends: Not as common in clothing yarns, but polyester or nylon-blended yarns (often used in sportswear or rugs) resist shrinkage. They’re usually machine washable and durable, though less breathable.
- Check Labels: Always read the yarn label – yarns marked “machine wash” and especially “tumble dry safe” are formulated to resist shrinkage. Crocheters note that yarns labeled “superwash” (for wool) or “washable cotton” often handle washing well. Many baby or children’s yarns fall into this category because they’re designed for easy care.
Seasoned crocheters often share experiences: for example, many report that an acrylic baby blanket stayed perfectly sized through dozens of washes, while a pure cotton dishcloth “grew up” and then shrank again if washed too hot. The trick is matching the yarn to your project’s needs and your comfort level with care.
FAQ Section
Does cotton yarn always shrink in crochet? Not always. Pure cotton can shrink a bit if washed with heat, but it depends on the yarn and care. If you wash cotton crochet in cool water and reshape it, it will mostly keep its size. Some cotton even relaxes during wear and then returns to size after washing. Using mercerized cotton or a cotton blend also reduces shrinkage.
Can I put crochet in the washing machine? Yes, many crochet items can be machine washed, especially if the yarn is labeled machine-washable (common with acrylics and many cottons). To protect your work, use a gentle/delicate cycle with cold water, and place your item in a mesh bag. Heavy or delicate pieces (like wool sweaters or fine lace) are safer to hand wash, but sturdy items like acrylic blankets usually handle the machine well.
Why did my crochet blanket shrink? The most likely reason is heat or agitation. If your blanket is made of wool or cotton and it was washed in warm/hot water or put in a hot dryer, it could have shrunk. Tight stitches or not blocking the blanket before use can also make shrinkage more noticeable. Double-check the yarn fiber (wool felts easily, cotton tightens) and the wash settings – even accidentally using hot water can shrink many fibers.
How do you wash crochet without it shrinking? Keep it gentle. Hand-wash or machine wash on the delicate cycle, using cold or lukewarm water and a mild detergent. Never wring or twist the piece. After rinsing, press out water (or roll in a towel) and reshape it flat. Air drying on a flat surface is best to preserve shape. Avoid any hot water or heat drying – these are the main causes of shrinkage.
Should I block before or after washing? Typically after washing. Blocking is done on a damp item. So wash or soak your piece first, then block it while it’s wet. This sets the fibers in the correct size. If you blocked it before washing, you’ll likely need to re-block it after. Some people briefly steam-block synthetic pieces, but generally the final blocking happens post-wash on a clean, damp project.
Conclusion
Even though the thought of crochet shrinking can be scary, it doesn’t have to happen to your creations. By following these guidelines on yarn choice, swatching, gentle washing, and blocking, you can launder your crochet projects with confidence instead of dread. Remember: cold, gentle washes and flat drying preserve size, and most shrinkage is easily prevented or fixed by reshaping. So go ahead and enjoy wearing or gifting your handmade items without fear — with a little care, they’ll stay just the way you made them.
