I see lots of people leaving bad reviews because they burned a hole in the fabric while trying to remove the wrinkles. There are several things wrong. First, it says to use a steam iron, this is NOT your regular clothes iron, it's a completelydifferent machine, look it up. Second, if you do use a regular iron, it clearly says not to exceed 90 degrees Celsius and that you should refer to the manual for your machine to ensure this. So if you say you "only put it on 2", it means you have no idea how hot it actually is and it's again your own fault if your burned it. This is a synthetic material, if you're using a regular clothes iron on a setting hot enough to make steam, it's waaaaaaaaay too hot. Steam irons (the other machine, the one it shows pictures of)make steam in a different way that doesn't involve a hot metal plate touching the fabric and vaporizing water on contact. If you're making steam that way, your iron is well over 100 Celsius and will burn this fabric, just like the instructions say. Now, if all you have is a regular iron, use a shirt in between your iron and the backdrop, only turn the heat up to where it's hot to the touch but where you can still momentarily touch it without burning yourself, much cooler than a curling iron, more like a blowdryer on high. There will be no steam, not even close, your iron will barely be above the min position in most cases. This is not a pair of pants or cotton dress shirt, it doesn't take much heat to remove the wrinkles. you could use ahot water bottle, military canteen, just about anything that can hold hot water and heats up on the outside and easily do this job without an iron. I dewrinkled two of these in about half an hour, just take your time and don't be stupid. Great backdrop, using as a greenscreen with no issues.
