Would it help if you wore a facemask when you were using pastels?

I did a lot of art in school. I was always motivated when there was a class, or figure-drawing sessions. Since I left school I just haven't been able to get myself to do it. I have to learn how not to be a perfectionist, which doesn't help, especially when i am so out of practice. I will keep an eye out for this art therapy scheme though, what a great idea <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
