My only experience with donating for a quilt auction was for the Christian school that my daughter attended. I made a throw size quilt and hand quilted it and it went for $250. I was pleased with that. There was a scrappy "Apple Core" bed size quilt that was hand pieced and hand quilted that I loved and it went for $600. However, there was another quilt that was a very simple pattern, machine quilted, but with beautiful fabrics and it went for $1400!! It just showed that people don't appreciate hand quilting and I was going to do one last year that was big, pretty fabrics and machine quilted, but before the auction came around, the school closed. But all the quilts went for very good prices. I would be sick to put all that work in a quilt and see it sell for $30.
