Update: I am almost done with the back and it looks like its going to fit my husband.
I have a question on armhole shaping. The pattern says Dec 1 st each side every RS row. This is what I do: Knit the first stitch and then do a k2tog. At the end of the row, when there are three stitches on the left needle, do k2tog and knit the last stitch. I do this because my k2tog stitch is loose and the yarn hangs a little bit and when I knit the next stitch, I can tighten this loose yarn.
Is it ok to do k2tog after the first and before the last stitch? The armhole looks ok, so I am assuming my method should not be a problem.
