How to block crochet
To block crochet, wet or dampen the finished piece, gently press out excess water, and pin it to the exact finished measurements on a blocking mat. Let it dry completely before unpinning. Blocking evens stitches, straightens edges and opens lace. Choose wet, spray or steam blocking according to the yarn fiber.

How do you wet block crochet?
Wet block crochet by soaking the piece, removing excess water and pinning it to size until dry.
- Soak the piece in cool water with a little wool wash for 15–20 minutes.
- Lift it out supported in both hands without wringing.
- Roll the piece in a towel and press to remove excess water.
- Lay it on a blocking mat and pin edges to the finished measurements.
- Leave it to dry completely, usually 12–24 hours.
- Unpin once the piece is dry to the touch throughout.
How do you block acrylic crochet?
Block acrylic crochet with gentle steam from a garment steamer or an iron held above the fabric, never touching it, then let it cool pinned in place.
Too much heat permanently flattens acrylic, which some crocheters use deliberately to add drape.
Which blocking method should you use for each fiber?
Use the blocking method that suits the fiber's heat and water tolerance.
| Fiber | Recommended method | Caution |
|---|---|---|
| Wool and merino | Wet block or steam | Avoid agitation and hot water to prevent felting |
| Cotton | Wet block or steam | Dries slowly; allow extra time |
| Acrylic | Light steam held above the fabric | Direct heat melts or flattens fibers |
| Bamboo and viscose | Spray block | Grows when saturated |
| Chenille and velvet | Light spray or no blocking | Pressing crushes the pile |
Do you need to block every crochet project?
Not every crochet project needs blocking. Amigurumi, baskets and many acrylic blankets are used unblocked, while granny squares, lace shawls and garments benefit noticeably from blocking.

Frequently asked questions
What do I need to block crochet?
You need blocking mats or a thick towel, rust-proof pins, a spray bottle or basin, and a tape measure.
Is blocking permanent?
Blocking is permanent for heat-set acrylic but must be repeated after washing for most natural fibers.
Can I block granny squares together?
Yes. Pin several squares to identical measurements on the same mat so they dry to one size.
