Our quilt shops usually carry Retayne, and it is available in small bottles on-line at Joann's, but not in their stores. Not all LQS's carry Retayne. You need to find an open-minded owner who will admit that sometimes even the best fabrics will bleed.
I think it is nice when gifting a quilt to include a couple of Color Catchers in the gift, as well as general washing instructions. If the person uses the Color Catcher the first time they launder the quilt, they will see by the Color Catcher's appearance whether or not they can expect future problems.
