I have made many quilts using used dryer sheets as a foundation. Scented and non scented, my nose could not detect any scent after being in a washing machine or dryer. I just sew the fabric to the sheets and used up all of my scraps that way. When I have enough, I make a quilt. It is an ongoing project for me. I keep a small bag for the dryer sheets, press lightly with a warm iron when I get ready to sew.
