Increase 1 stitch by knitting into the front and back of an existing stitch.

1 Insert the tip of the right-hand needle into the front of the stitch and knit as normal, but don’t drop it from the left-hand needle. 2 Then take the right-hand needle behind the left and insert the tip of the needle down through the back of the stitch on the left-hand needle. 3 Wrap the yarn round the tip of the right-hand needle to knit the stitch. Bring the needle through to make the stitch, keeping it on the right-hand needle.
