So I am one of the many knitters who do not block ever knit piece. But after some research into the importance of blocking, I have changed my thinking about blocking. There are three methods of blocking, steam, wet, & spray blocking. We will be looking at each method.
The method of “Steam Blocking”, is as it sounds. there are two ways to steam block, you pin your piece, and then steam iron with or with a protective piece of fabric. This method works best nature cotton, and other materials that do not react well to water, or fibers that are not man made.
Wet Blocking, is where is the piece is completely wet (but not dripping) and then stretched and then pinned. Ensure that you are using rust proof pin. Once the piece is pinned, you do not want to fuss with it too much. again you are wanting to stretch the piece to the shape/size that you are wanting. The best way to gage the shape/size, use some kind of a measuring devise like a tape measure.
Spray blocking is the most gentle method. This would be used for the very delicate materials, like silks or other delicate fibers. Again you want to pin your piece to shape, then using a spray bottle lightly spritz the piece.
There are specially made equipment for blocking. The most common tool for blocking are the “”T” pins. Blocking boards have predetermined measurements, so easy measuring. Another took used are blocking wires. These wires are woven through the edges of the piece. The wires can also be used with pins, if desired.
