The steam treatment works great. Some time back I posted a thread here on the bb looking for peacock herl subsitute as the herl I have been finding lately at the shops have not looked all that good. It finally dawned on me that I read an article or thread here regarding the use of steam to revive materials. About a month ago I pulled out of storage my Norelco travel steamer and tried it on a strung of herl I bought that was looking so so. The steam put the life back into the herl. :D
