I am making this pinwheel blanket : http://www.knitlist.com/00gift/round-baby-blanket.htm
I am about 450 stitches into it and in my previous row I have found a mistake. I knitted a stitch where I should have put a yarnover. As I worked around I have come to a knitted stitch instead of my loop over the needle. Is there a way to drop this stitch and make it into a yarnover? I really don't want to tink 450 stitches......HELP!
