I had an interesting experience recently. I made a quilt, batiks, simple Chinese Coin pattern, maybe twin size... Donated it to a private non profit organization for a silent auction. I had a jelly roll, some batik yardage, backing and batting. Maybe 75 bucks or so. It was machine quilted and that work was donated as well, but it would have cost $80 or $85 I'd guess. They had a professional value it for the auction and he said it was worth at least $950. Amazing!
