Your quilt is lovely. After reading your post I was looking at it from the point of a consumer and not a quilter. If I were to purchase a quilt I would assume that the fabrics are pre shrunk and if there was bleeding, a wash in Synthropol. Also that the recommended batting and stitching be used to avoid bunching.
I do not sell quilts, but I follow this procedure for my own quilts and gift quilts. Just a thought.
