Finally a mop material that is easy to get and works! This new material from Hareline works great for tying the infamous mop fly. The problem with tying mops in the past was finding the materials in a color that works consistently. You would find a color that worked, and then after you ran out, you couldn't find the material in that same color again. Well problem solved! We really like these in the Cheese color and the White. Give em a try!
