I am knitting a sweater sleeve. The pattern says increase at each edge of every 4th row 11 times. Question #1: Does this mean both the left and the right side? Question #2: Which stitch do I increase in, and what is the best method to use for the increase? I tried a couple of ways, but I don't like the stair step look I get with increasing in the last stitch. I tried doing the next to the last stitch and I end up with a hole? any advice will do.
