A little randomness in tying. A size 16, Emerger pattern tied to sit low in the film, and sink a bit at the end of the presentation. The Z-lon tail/shuck could be left off and the pattern could be used as a low riding Caddis pattern. Each one looks different, (not unusual for me) as I experimented with hackle color, thread color, body material (thread or dubbing) and thorax color/material. Same techniques to tie but different outcomes.
