L4FF Catgut Biothread
Catgut Biothread is one of the best, natural fly tying materials used for tying nymphs and larvae. This fantastic fly tying material is opaque when dry and becomes milky translucent when wet. This Catgut Biothread will be stiff out of the package making it difficult to work with so we recommend that you get it wet before tying with it. Cut the section of material you want to work with and soak it in warm water for 3 to 5 minutes. The color will change from the opaque to milky transparent. Use different color threads for different effects on the end product. It is a magical material and is absolutely fabulous for making bodies for nymphs, emergers and larvae. 1 meter or 3.28 feet per bag. Poland.
