Working with epoxies, modifying head cements and using UV-protected acrylics can give even experienced tiers headaches. While the end result of using these materials and techniques yields attractive and effective flies, sometimes finding a place to mix these substances is difficult. Loon Outdoors’ mixing cup is a simple solution you will love. It’s unbreakable, seals to just about any smooth surface and will not bond to cements or epoxies. The instructions are simple: Mix your epoxy or cement in the cup, use for tying, and once the material has cured, turn the cup inside out to pop out the hardened adhesive.
