I felt the same way at my guild's show a few years back and made a suggestion that worked wonders. I set up a quilt boutique for quilted and other finished items, but accepted all donations and sold them on the other side of the building on a rummage sale. This way everyone donated items that were up for sale, but the rummage sale items didn't take away from the beauty of the finished items. Some people love to buy other people's unwanted items but don't buy finished items because they can make them themselves, while others prefer finished items because they can't sew. No need to keep them mixed up. Unsold items from the rummage sale were kept for the following show while for the finished items we gave everyone the option of taking them back or saving them for the next sale. Most people didn't want them back. Even if the items are not perfect, presentation is everything and with the right display, most people cannot tell they are not perfect. Good luck. This is a huge project to take on.
