How about some organza ribbon. Slice it up the middle and pick out the horizontal fibers. It will leave you with an organza "hackle". tie it in, put a good dollop of Zap a gap on, and wind it around. It will flair like hackle, but hopefully be more durable and add alittle flash as well. I use the same technique for collars on caddis pupa, and it has worked very well.
