For those samples that refuse to part with the glued on paper strips, we use the cloth part, too much trouble trying to get it all off on some of them. We have made quilts out of the fabric, large and smaller pieces and gave them away to charity. Even pieced some of the larger ones for backings. Wear like iron and cheap when you get them free.
Just cut off the parts where the paper won't come off and save your time, water don't seem to remove the glue.
