I have been doing craft shows for17 years now and had a tendency to always go low. While in some parts of our city the people you are selling to are low imcome but most of the schools and churches have all incomes. Then we have some really big show like during the international ballon festival. I found that when I upped my prices so that I felt like was getting paid for my time I sold more. People won't value your work unless you do. If I wanted to only pay 300.00 to 500.00 for a quilt I would go to the flea market or hit the estate sales. You want to be known by the quailty of your work not the quanity.
