Stonfo Fil Tec Art. 594 is a flat synthetic fly tying yarn featuring excellent elasticity and a distinctive opalescent finish. Its unique flat profile creates smooth, realistic bodies while the subtle light-scattering effect produces natural reflections similar to those seen on insect cuticles and aquatic organisms. It is equally effective for tying lifelike imitations, attractor patterns, legs, antennae and other fine details. The material can also be easily coloured with permanent markers, allowing fly tiers to create custom shades and realistic colour transitions.
