Blocking is the final step where you shape and set your finished piece to its intended size and drape. It helps:

  • Even out your stitches
  • Flatten curly edges and lacework
  • Open up textures (like cables or lace)
  • Give your piece a polished, professional look

What types of blocking are there?

Section titled “What types of blocking are there?”

There are three main blocking methods: wet blocking, steam blocking, and spray blocking. Your choice depends on the fiber content and the effect you want.

Wet Blocking

Section titled “Wet Blocking”
- Check the yarn for pressing or special instructions
- Soak the piece in water (or gently wash)
- Gently squeeze out excess water (do not wring)
- Pin it to a blocking mat in the desired shape and measurements
- Let it air dry completely

Best for natural fibers like wool, alpaca, and cotton

Steam Blocking

Section titled “Steam Blocking”
- Check the yarn for pressing or special instructions
- Pin the item in shape on a blocking mat in the desired shape and measurements
- Hover a steam iron or garment steamer just above the surface (do not press directly)
- Lightly steam the piece and let it dry

Great for acrylics and blends. Softens without melting the yarn

Spray Blocking

Section titled “Spray Blocking”
- Check the yarn for pressing or special instructions
- Pin the dry item in place
- Mist lightly with water from a spray bottle
- Let it dry completely

Ideal for lightweight fabrics or gentle adjustments

When should you block?

Section titled “When should you block?”

Block before seaming pieces together and after finishing lace or textured projects. It helps edges lie flat and stitch patterns open up.

  • Before seaming pieces together (like in sweaters or motif blankets)
  • After finishing a scarf, shawl, or lace project
  • When edges curl or the stitch pattern needs to open up

Does every project need blocking?

Section titled “Does every project need blocking?”

No. Blocking is optional for dense fabrics, dishcloths, and amigurumi toys. These projects hold their shape well without it.

What tools do you need for blocking?

Section titled “What tools do you need for blocking?”

You only need a few basic tools: blocking mats, rust-proof pins or wires, and a way to apply moisture.

  • Blocking mats (foam boards or towels)
  • Rust-proof pins or blocking wires
  • Spray bottle or garment steamer
  • Tape measure or ruler (for sizing)
