Oh, I have the Complete Idiot's Guide!
I didn't even think about looking at a diagonal dishcloth and just continuing on! (D'oh!)
NOW, how much yarn will I need? That is the question. I have some LSU colored bulky yarn, 3 hanks, but I can't remember how many yards are in each.....better go find out. I need to find some use for it. If it's not enough, I'll have to buy more. It never ends!!!!
