Golden stonefly adult

....made with 1/4" thick 2lbs per cubic foot EVA closed-cell foam,
elk hair and Zelon. The Zelon legs get "sewn" in place with
a needle whose eye has been widened with heat and another needle.
Every thing is lashed loosely in place (so not to collapse the foam)
and then glued in place with thin ZapCA super glue.

Floats forever. Can't sink it. Fish byte it.
Unfortunately, the only source I know for 2lbs per cubic foot EVA
is wholesale only. And not to the fishing industry.
But I'm working on it. I have a new friend, who sells fly tying stuff.
I'll work on him.
