First Step

Prior to tying, soak the part of Catgut Biothread that you want to use in warm water for 3-5 minutes. The color will change from opaque to more milky and transparent and the material will be super-flexible and easy to wrap. When the fly dries, the body will go back to its solid-colored state.
