Blocking basics
How to block crochet to even stitches and sharpen edges, and which method suits which fibre.
Blocking is the finishing step that many people skip and then wish they hadn’t. It evens out stitches, sets the shape and opens up lace.
What you need
- Interlocking foam blocking mats, ideally with a printed grid.
- Rust-proof pins or blocking wires.
- A spray bottle, or a basin for soaking.
- A clean towel.
Three methods
- Spray blocking. Pin the piece to size, spray it until damp and let it dry. Good for cotton and light shaping.
- Wet blocking. Soak the piece in cool water for 15–20 minutes, gently squeeze out the water (do not wring), roll it in a towel, and pin it to shape. The strongest effect.
- Steam blocking. Hold a steamer or iron just above the piece and do not touch it. Suitable for wool and cotton, not for acrylic.
A warning about acrylic. Steam can permanently limp or “kill” acrylic. Test on a swatch first, or use wet blocking with cool water.
Tips
Pin at regular intervals along the edges. Do not stretch the piece past the size in the pattern. Leave it undisturbed until completely dry, which can take a day or more.
