The NMF is suitable for setups where just a few extra turns can quickly change the body’s silhouette. Place it on a base of already-thin wire, taking care not to cross the coils. On a small submerged fly, a discreet wrap is enough to define the segments. For an emerger, keep the abdomen bare if most of the volume needs to remain around the thorax. The spool contains 100 meters of Micro Floss.
