I think it is like cooking. We determine the ingredients based on the use. It is just supper for the kids, and a rework of leftovers, or is it for a dinner party? Quilts are like that. If I were to ever try to make one for competition, I would use the best materials and make my back look as good as the front, but for the grandkid's bed, a sheet works great. we all know there can be a great difference between bedding and art.
