Thanks for this chart - it's really useful! I've been trying to figure this out myself! I'm new to making my own flies but so far it's pretty rewarding and it's fun looking for materials at various craft stores that I can make use of. Tons of fun! Oh, I discovered an online source that sells nice little tins that I can use for holding my flies too. They consider themselves a supplier of soap making supplies but their containers can serve other purposes as well.
