Troutline Catgut Biothread

Olive Brown
Caddis Green
We have the pleasure to offer you one of the best fly tying material used in tying nymphs, Catgut Biothread. This fantastic fly tying material has an opacity aspect when is dry and when gets wet become milky translucent. When is dry the material is stiff and a little bit difficult to work with so we recommend to  be used  wet.
For that, you should keept he material  for 3-5min in warm water only the part that you want to use. The color will change from the opaque to  milky transparent.
If  is used different threads in different colors the nymph will have shades in the under body color.
It is a magic material and is absolutely fabulous for making  bodies for nymphs and emergers.
