Folks,

I want to thank everyone for your help and suggestions. As I suspected, I've got plenty of dubbing that will substitute well for Scintilla. Sounds to me as if any moderately sparkly dubbing will fill in very nice. I did a quick search on Goggle and it seems that Scintilla has been discontinued though some suppliers like Jamie seem to have a good supply. Others are listing it as going, going, gone and have only limited colors left. Three shops have listed their Scintilla as hard to find and rare so if you have a favorite color, you might want to order a couple of packs while you can from Jamie. Typical of the warning are message posted by Fly Tying World:

"This classic dubbing is being discontinued and extremely hard to find. Selection is limited to stock on hand, while they last. Better get it while you can."

Once again, thanks for your suggestions. 8T
