Perhaps if my quilts were exquisitly beautiful and I had plans to enter them in shows, then I probably would not use sheets for backing. However, I make them to be used and make them because I enjoy doing so. Most of them time I use 200 thread count. I do have some that are higher and will try them in the future. I bought them at a great price on sale. I guess the quilt police will have to add me to their list as well. Bottom line, if you are making your own quilts, quilting them yourself and have no problems doing so, what difference does anyone else's opinion matter????
