Yesterday I was determined to figure out where I when wrong with Susan! So I asked two of my knitting friends for help. Always good to get multiple views!
First, I put a life line in the row below the first armhole bindoffs. All three of us counted twice before agreeing that I had the exact number of stitches called for in the pattern.
I check for the correct number of armhole decreases, and placed another lifeline. More counting by all three of us. Surprise! Two stitches shy of the number required by the pattern. I knew that 2 was the magic number because I had four stitches on the needles when I stopped knitting and I needed six! But where did I lose 2 stitches?? Back to the pattern. Reading it aloud to my friends, I found this line: next row (RS)
