my regular knitting looks like really thick purling, and my purling looks exactly the same. Ocassionally, either the knitting or purling will show up as regular knitting, but really thin. I don't know why or how it does this, or what I'm doing differently to change it back. I'm so confuzed, i've watched the videos so many times, but can't figure out what i'm doing wrong. Any Ideas, or is it hopeless?
