Backside materials such as vinyl plates Body Stretch, Live Body and foils as Shellback, Flashback, and Pearl Scudback are indispensable tying material for the production of freshwater shrimps, caddis larvae and all types of Czech Nymphs. By using such material in combination with regular ribbing, we create a shiny, segmented and naturally acting back of nymphs. In addition to the above-mentioned materials, you can find in this category other synthetic foils that are used for example to imitate eyes while saving natural resources - Jungle Cock, or different segments of nymphs back and wings of dry flies.
