I just tied up a few for a fly swap on another site. There are several ways to tie them using different materials. You can save a bundle by getting the supplies at Michael's art supplies. You buy a sheet of foam, a package of silver leaf, and a package of gold leaf. You can buy pre made cutters or you can just draw a template. I used a glue gun on that batch but have since discovered Clear Cure Goo which I will use from now on. It's the perfect replacement for epoxy.

Ron Dong out in California has taken Joe Blados design and tweaked it some creating a wonderful very fishy looking fly which has become a go to fly in Baja for Dorado, Tuna, Roosters etc. You can learn to tie them here
