I know there's a way to do a burn test to find fabric content but I don't know exactly how to do that.
Good advice. I found several burn tests on line, tried it and one of the two fabrics literally melted in the ashtray. It was obviously a blend of some kind. The cotton didn't even want to burn and when it did, it just left a really fine ash. Thanks.
