I bought vinyl as fabric (by the yard) to use as table cloth on a very long (11-foot) table. I ended up buying everything they had an that roll, and the remainder of it was rather wrinkled. How can I remove those set-in wrinkles? Iron? Steam? It’s at the vacation home, so I don’t have very many gadgets there (but I do have an iron). I need to be careful not to damage the vinyl. Thanks!
