How to Iron a Tulle Prom Dress. Your beautiful tulle prom dress is wrinkled and you don't have time to take it to the dry cleaners. You can iron it, but you must be careful when ironing tulle because it is made from nylon and will melt. Here's how to get the wrinkles out before your date arrives.
Set your iron on the lowest heat setting available.
Place a towel on top of the tulle so that you will not burn your dress.
Move quickly so that the iron does not sit in one place for too long, which will cause melting, or worse, burning of your beautiful tulle prom dress.
Use the steam feature on your iron. With the towel placed on top of your dress, hit the button on your iron for steam. Remove the iron and the towel to make sure the wrinkles are coming out and you are not damaging your dress.
