The clothes steamer I bought at Home Depot works just as well on Wool, PV or the SWK Acrylics at getting all manner of wrinkles out of a kilt. It even managed to resurrect the creases on my new SWK blackwatch after I passed out on the couch from absolute exhaustion (and a little bit too much scotch taken to ease the pain on my leg) after working far too many hours straight on a commission recently. The dog and I slumbered for hours, but it sure did a number on the kilt since I had pretty much flopped down and gone unconscious in one swift motion. (Of course, it took a lint brush to get all the long blond doggie hairs off my kilt!)
