There is a quilt shop within driving distance that gets salesmen's samples of cotton fabrics but not on the header cards. They are usually groups of 4 to 8 colorways in various sizes similar to what you saw. Owner bags these into 2.5 lb. bags and sells them for $7 each on special sale days such as Super Bowl Sunday. I have purchased them many times and always find enough fabric that I like to be worth the $7. What I don't like, I either use in charity quilts, trade or donate. Love, love, love these bags.
