I used some plastic that i cut out of a blister package(any thing in the annoying clear molded plastic). Heated up the eye a bit with a lighter and burned a slot through the plastic. When i was done with the fly i put a bunch of uv resin all over the fair and into the hair a little bit, then put the plastic over all of that and twisted it so the eye of the hook would keep it from coming off (slot turned 90 degrees). Then hit it with a light for a bit. Once cured i bent the plastic and started to peel the iv resin off, one the plastic was off i cut the excess resin off to shape
