It is really hard to make money with quilts. People in general don't value the creative Women's Arts that used to be a homemaker skill. Unless you happen to be Amish, Gee's Bend, or some other known group. I know it must be disappointing to put in such a great effort and not have the response you expected. I have wondered what sells at shows. I hope it just means finding the right show to display. I know I make my quilts for me and share when someone expresses an interest. So enjoy it for your creativity and expression.
