UNI-Flexx is another great product from UNI Products. Great for bodies, legs, and tails on a multitude of patterns.
UNI-Flexx is a fine, flat elastic strand. It can be used for rubber legs and skirts. Some like it as a floss replacement because it is much easier to handle. You may also use it for bodies on small nymphs, larva, and pupa. The stretch permits the material to be laid on the hook with a variety of tensions, thus reducing or avoiding slippage. In many cases it is not the stretch which is most important, rather the texture and stiffness and availability in a variety of vibrant colors. Moreover, the material retains the original color when wet. As usual, uses are only limited by the tier's imagination. 1680 Denier. 15 yard spool.
