All hair spary will wash out so the residue is not a problem. It's hard to find plain old hair spray. We use to use it in art class to keep chalk from smearing and I have seen hand quilters use it to keep the chalk quilt markings on the quilt top from rubbing off. Here is a recipe that works for basting. I use it instead of buying basting spray.
