RAINY'S S-T-R-E-T-C-H FLEX: An unbelievably strong and durable elastic material. Tie worms, scuds, nymphs, stoneflies, and more!
Used heavily by the lake addicts for chironomids and the river addicts for stonefly nymphs.
Overlap each wrap for easy segmented bodies. Also works very well for wingpads and scudbacks. In 1/8" wide strips.
