I am tracking the 3-4 days of rolling, hanging and steam ironing which they claim removes wrinkles from this thin vinyl. NO! They will NEVER smooth wrinkles. In fact, even with their recommended steam ironing process, the product deforms (stretches) somewhat, leaving creases and wrinkles. I sent it back and received a polyester background. I wet a towel and threw it in the dryer with a polyester backdrop and in 5 minutes I had a wrinkle free backdrop. Save yourself headaches, frustrations and frustrations, spend a few bucks more and get better stuff.
