Kim is very good to answer questions about the spray if you email her. It works on cotton batting but I found it did not work on polyester. You have to wet it pretty well and iron it dry. I didn't care for the mess on the iron and the time it took. But it is a trade off of time versus money. I've found lots of posts online about using it.
