If you Google, you will probably come up with a website or two by people who have tried it. One I read said that she created a small quilt sandwich and washed it, and it seemed to come out in the wash, same as quilt basting sprays. I spent some time Googling it and even found the MSDS for the Elmers that lists what chemicals are in it and safety concerns. It is very flammable, but I think all basting sprays are. This is not the same as washable Elmer's glue which is made up primarily of starch. If you read the chemicals list for the spray, there are a lot of different chemicals in it.
