I use this iron on vinyl. When I make hand sewing thread catchers, the inside fabric will not "let go" of all of those threads - so I put the vinyl on the INSIDE lining. When you dump the bag all of the thread and lint comes out! Also for the serger thread catcher. Just makes sense to me. You can add it to changing pads you can make to match the nursery. I don't know that I would use it with quilting in any way.
