Mr FishinfellaS tends to prettier flies than I do. I found that out when he gave me one of his damsel imitations.

Here's mine (simple version). Pick the appropriate sized hook (#10 or #12 3xl), put a chear rochelle bead up on the head (that's the silver lined ones). wrap the body with red wire. Tie off.

I did these as my intent was to have a fly that would sink fast and be a good bottom fly on a two fly rig.

Ron's cosmic fly is probably prettier.
