Misty Fuse! So light and soft, I even have used it to baste quilts (leftover scraps) and can FMQ right through it. Also environmentally friendly and solvent free. Buy in bulk on Ebay, wayyy cheaper!
Anything that works is fine for me. I have several in my collection and have no qualms about any of the lite weight ones. I like Pellon fusible for my totes.
