This is our favorite egg material. You can tie over 100 eggs with one pack once you get the hang of it. Simply tie in the yarn much like you do a chenille and give 2-3 wraps around your hook of choice - ours is a curved shank 1-2X strong hook. Easy as that, you've got an egg! This material gives you the bulk you want in an egg, but allows the fly to sink faster and get in the zone compared to traditional yarn eggs.
