Egg Yarn: Glo-Bug Yarn and McFly Foam
I use the Glo-Bug yarn for my Glo-Bugs, Yarn Bubbles, for the Veil on Nuke Eggs, as well big bright butts and heads on some Steelhead patterns.
I use McFly Foam for the center nucleus in my Nuke Eggs. The McFly foam makes it easy to get a very round Glo-Bug particularly on very small eggs.
