Do not undervalue yourself and your skills.
Think about this: One of the things that drives some of us nuts is how girls and certain women think they're not good enough - not pretty enough, not skinny enough, not big enough boobs, etc. Right? And some of us get over that and some of us don't.
Well, the same goes for our quilting. We need to stop critiquing and denigrating our work and thinking it's not worthy, especially since it's a "hobby". Just because it's a hobby doesn't mean we shouldn't get paid. We need to get over that, too. There are lots of people who get paid darn good money for their hobbies.
I recommend this excellent post on the subject.
