How to Make 1
One form of increasing in knitting is to work into the strand between two stitches. This increase is called a make 1, because you make a stitch by itself, instead of using a previous stitch. It is less noticiable than knitting into the front and back of a stitch.
1. Insert the left needle from front to back under the horizontal strand that runs between the stitch on the right needle and the stitch on the left needle.
2. Insert the right needle under this strand through the back loop.
3. Knit through the back of the strand to twist the new stitch and prevent a small hole.
