Wet Blocking

Wet blocking is the standard finishing technique for almost every knit project. Soaking the finished piece, then pinning or laying it flat to dry, evens out tension, opens stitch patterns, and sets the final dimensions.

Method

Fill a sink or basin with lukewarm water. Add a small amount of wool wash. Submerge the piece and let it soak for 20–30 minutes. Drain and gently squeeze out (do not wring) the excess water.

Towel rolling

Lay the wet piece on a clean towel. Roll the towel up tightly with the piece inside. Press to absorb excess water. Unroll and transfer the piece to a blocking mat.

Pinning or laying flat

For lace and shaped pieces, pin to final dimensions on a blocking mat. For sweaters and unshaped pieces, lay flat in shape and let dry without pinning. Drying time: 12–48 hours depending on yarn weight and humidity.

Yarns to be careful with

Superwash wool grows when wet — block to slightly smaller than final dimensions. Cotton and linen also relax significantly. Always wash a swatch first to check.

Tips

  • Use lukewarm water to avoid felting.
  • Squeeze, never wring, to remove water — wringing distorts the stitches.
  • Always wash a swatch before blocking a finished garment to check for shrinking or growing.

In depth

Wet blocking works because wet wool fibres lose their structural memory temporarily. The soaked fibres relax, allowing the fabric to be reshaped, and then "remember" the new shape as they dry. The result is a finished piece with even tension and the dimensions the pattern intended.
