The most popular use for Stretch Tubing is as a segmented body for midge, caddis, and scud patterns. All that is necessary for these flies is to tie in the tubing and wrap it over the hook. Many fly tyers tie the tubing in at the rear of the hook and simply wrap it forward, producing a functional fly. However, by tying the tubing in near the front of the hook (perhaps behind a bead), wrapping it back and then forward over itself, the fly will be more nicely tied.
