Increasing in knitting is a technique used to add stitches to a knitted fabric, creating a wider or more shaped piece. This can be done in a variety of ways, each with its own advantages and disadvantages.
One common method of increasing is to make a yarnover, which involves wrapping the yarn around the needle before knitting the next stitch. This creates a new loop on the needle, which can then be knitted as usual. Another method is to knit into the front and back of the same stitch, which also creates a new loop. This method is often used to increase at the beginning or end of a row.
