Oh, pish posh, you are not ugly! Actually, I have no idea if "pish posh" is appropriate here (I'm not sure exactly what it means) but I've always wanted to say (or write) it.
Anyway, I don't think you have to be all that skilled for the show to work. You are a funny, personable guy knitting in a truck stop. That's why people would watch.
Maybe you're show could focus on beginner knitters?
