Some of those quilts in the big juried shows take years and a LOT of money to make. I read that one such quilt at the Houston Quilt Festival last fall was valued at several thousand dollars and it took 10 years for the maker to complete it. I'm not certain, but fairly sure that quilts like that don't end up on a bed. ;-)
The quilt Midnight in the Garden of Good and Elvis was valued at around $6500 when it was destroyed at the Houston Quilt Festival back in 2002. I'm certain that some of those quilts are probably valued at much much more these days. I can't imagine making a quilt worth that much!
