Rated 5 out of 5 by from Easy egg pattern Am Orvis sales associate showed me how to tie an egg pattern with McFly foam. It works great; only a couple of minutes per fly.

Rated 4 out of 5 by from Good egg yarn This is heavier than my other yarns. I can use less and still get good action in the water.

Rated 5 out of 5 by from Reliability and quality I need or can't find locally. I try to go to the local store as often as I can just because of the "drool" factor involved and being up close and personal with the merchandise. They are always a big help when I need something or I am not sure of what I need and I know that I am getting great quality in my purchases.

Rated 5 out of 5 by from Best Egg Yarn This is simply the best egg yarn for great lakes salmon and steelhead patterns. The elastic in the yarn will make those glo bugs nice and round. Mccheese eggs are a must.

Rated 4 out of 5 by from The easiest egg yarn one can use to tie Glo Bugs. It doesn't have the same sheen as Glo Bug yarn, but this can be mimicked with a veil.
