Blocking is the process of stretching and shaping your finished items to create the correct dimensions from the pattern. It is also really useful for ensuring hat pieces to be joined fit well together. There are a few different ways to achieve this, so check the information on the yarn ball band and pick the most suitable option.
Dampen the pieces so that they are wet through and gently push out excess water. Spread the sections out on a towel to air dry. Use a tape measure to ensure each part is the correct dimensions to that of the pattern and pin into the required shape. For a more gently option, try pinning it in place and lightly spritzing with a water spray. This is ideal for really delicate materials like cashmere which can be damaged by too much water.
Steam iron blocking
Place a dampened cloth on top of the separate sections of your knitting. Work gently over this with a very hot iron, be careful not to let the iron come into direct contact with the knitting as it can damage the work. Continue to press the work until the cloth is dry and the knitted fibres have been loosened by the steam. Then, pin the pieces to the desired shape and measurements and leave to set.
