Blocking in knitting is a simple but vital step that can greatly improve the look of even the most beginner knitting. It is a finishing technique that can be applied to almost all patterns and can prevent curling and lead to an overall nicer stitch definition. Blocking is the process of wetting the finished piece, making it more malleable, and then pinning it into the desired shape. As it dries, the newly formed hydrogen bonds will ensure that it will keep the shape. There are two main ways to block knitting projects: wet blocking and spray blocking. Wet blocking is recommended for wool and animal fibers in general, while spray blocking is recommended for delicate lace projects, cottons, and for gently refreshing garments between wears.

To block knitting, you will need some tools such as a basin or sink, towels, rust-proof T-pins, a measuring tape, pattern schematic or finished measurements, and sock blockers (for socks only) . Optional tools include Soak wash, blocking mats or a blocking board, and a set of stainless steel blocking wires for perfect, straight edges.

To wet block, you need to fully wet the finished piece, gently squeeze out the excess water, and then lay it flat on a towel. Roll up the towel with the piece inside and press down to remove more water. Then, lay the piece flat on a blocking mat or towel, and pin it into the desired shape.

To spray block, you need to fill a spray bottle with water and spray the finished piece until it is damp. Then, lay it flat on a blocking mat or towel, and pin it into the desired shape.

It is important to note that blocking is not always necessary, and whether or not to block a garment is a personal choice based on the project.
