Thanks, I forgot to say to cut the mono to form a taper for the belly (long to short). You can also use a little color on the inside to create a look of a stomach.
I've seen patterns simular to this in pictures using flex tubing to form the shape of the fly. I liked the look but wanted someting a little more durrable, so I came up with this idea. I'm sure it's been done in the past, but I just like the way the mono thread and body material seem to disapear with the application of epoxy.
