Salmonmac: actually, yes--it is that pattern.
I think what the problem is that maybe I misunderstood something? I've asked other people and while they weren't able to fully help me, what they told me got me to thinking. So, when the pattern mentioned "working from the armhole edge," I thought that meant to do the binding off and decreasing from stich holder on the right side, which has 36 stitches. Now I think that what it meant was to do all that from the middle stitch holder, with 28 stitches (is this right?). So if that's the case, do I just bind off the stitches on my right stitch holder? That's where my next row starts, and I don't think I can bind off and decrease the stitches in the middle without doing so.
Thanks in advance to whoever can help me.
