I have a homemade jig about 36″ long, measured in one inch increments which allow a string to be made for any bow. Ingredients are wax, B50 dacron string, usually three colours but have made two, most in dark brown, tan and black, scissors, glue, leather for burnishing and melting wax into strands. Always have trouble with serving ends and now use the eyelet on a needle to bring back the tag end under the serving.
