hand held steamers are the safest way to iron out wrinkles on delicate fabrics. Also, they're great to have for a quick touch up on your clothes and they get out wrinkles your iron couldn't. If I was on a desert island, my steamer would be in my life bag lol.
If you have a steamer, that works really well. I think that's what coach uses when they sell the floor model of a scarf/ponytail scarf
