Crochet blocking tools: what each one does

Use a flat measuring surface and supports that suit the yarn’s care method. Buy boards or pins only when the project needs controlled shaping.

Start with a ruler, a flat surface and a clean towel; add pins or a board only when a shape needs holding.

Set up without forcing the fabric

  1. Read the yarn label and finish a swatch with the intended method. Choose a surface that will not transfer color or be damaged by moisture.
  2. Lay the piece flat and measure it. Place supports around the intended outline without pulling stitches beyond the target shape.
  3. Keep sharp points out of the working area and remove every pin before moving or using the piece.
  4. Let the work reach its stated drying condition before measuring it again. Store pins and boards dry.

Check the pins and the yarn label

The manufacturer’s heat or moisture rating describes the accessory. It does not mean the yarn can be steamed or ironed.
