Giant freak legs?

I have almost one leg warmer done. I really think they look nice...except for this one part where I somehow wound up with an extra stitch and now there is a small hole there that probably only I can see but it bothers me. So I tried them on this morning and for some reason they make my legs look HUGE. I mean like crazy work out woman huge. I don't understand it. My legs are pretty normal looking without the leg warmers, and I don't think they are very thick...but when I put them on it looks like I'm she hulk. Crazy. I will post some pictures later.
