So, just to be clear now on how I would actually DO the bind-off....this is what I'm thinking:
So I would knit the first half of my row, up to those 4 center stitches that I'm going to bind off...then knit the first two of the center 4 ([size=2]ie. leave the first half of that row completely out of the bind-off....that's where my mistake happened on my tank, I think I accidentally bound off the last stitch of the first section of the row rather than the first stitch of the middle section...whew, sorry run on sentence)[/size], bind off the first one, etc. until I have bound off four stitches. Then in my mind I can't visualize where my working yarn will be at that point. It will become clear when I actually do it I think.
