I bought a couple CHI irons a number of years ago. One to keep on my pressing station, one to keep near my quilt frame to use when I needed to steam out excess fabric. It's around 25% humidity down here in my basement and I have no issues with static electricity which is surprising. Usually when I'm quilting, I'll fill my sink up with steaming hot water to add a bit of humidity so I don't get zapped plus I have a rubber mat going across the front of the frame plus rubber sole shoes and I have yet to get zapped. Don't know why but I'm happy just the same.
