I was told to use Heat 'n' Bond for a T-shirt quilt. Wrong stuff. The presser foot would not slide on it and it wouldn't slide under the presser foot because it was sticking to the machine bed on the left side. I had to put a piece of trash fabric on the machine bed, sew a line of a few inches and then re-position the trash fabric. And be careful that I didn't sew the trash fabric into the seam. What a pain. This item may have helped me, but of course my machines are not in the list that would accommodate it.
