Anyone ever use mcfly foam for a glo bug? I tried tying them using glo bug yarn but they always came out loose and wouldn't hold their shape. I picked up some mcfly foam this weekend to make one last try at tying a glo bug and this stuff works great. I used a 4" piece, doubled it over twice and tied it with 3 wraps, then 3-4 wraps around the base of the foam and whip finish. Makes a tight, round egg with no gap on the bottom of the hook.
