The tip about the Steam from a tea pot from Aurthur P is great. I was amazed the first time i did this. Just let your feathers dry naturally and shape them back as best you can by hand. Put some water in a teapot and put on the stove to boil. When the water starts to boil and steam starts coming out the spout simply hold the feathers in the steam and slowly rotate for 20 or 30 seconds. They'll be as good as new.
Great tip.
