I don't know where I read this - could have been on this board. It was about cheap hairspray and using it instead of temporary adhasive spray. I bought the cheapest I could find and tried it on a small lap quilt. It worked fine. Of course, it washed out with no problem. I'm going to try it on a larger piece to see if it holds just as well , but it does seem to be sticky enough. As you know it's waay cheaper than a "proper" basting spray!!
If this was a posting by a board member then, thankyou very much.
