You know I love to quilt with the blends. My mother in law made quilts for all my kids that they used all the time and because they were cotton they didn't hold up well in the wash. My blends can be washed over and over and hold up well. Not that I don't use cottons too but I think the cottons of today are made better. And I learned that you had to use cotton thread with cotton as the poly thread cuts the fibers in the cotton. I have wondered if that is what my MIL did.
