The edge of your knitting is very important, especially if it's going to be the finished edge of your work. When the edge of your work is going to be exposed using a slip stitch at the edge is the perfect way to create a smooth, attractive, and even edge stitch. There are a couple of ways to do this in your knitting that create different effects. There are also some times where it's not a good idea to work a slip stitch at the edge of your work. This would be where you need to pick up stitches along the edge after you are finished. Usually you pick up in a ratio of 2 sts per 3 rows or 3 sts per 4 rows. When you have a slip stitch edge it creates one 'slip stitch' for every 2 rows
