The hairdryer works well as long as you do it before they get too bad. If they are severely wrinkled the hairdryer won't work. That steam trick seems like a good idea.

Next time I'm going to try to use a clothes iron. I figure you can put the iron on steam, lay the vane on an ironing board, cover it with a cloth, and steam out the wrinkles. I'll let you know if it works!
