I'm a crap tyer and an even crappier dry fly fisher. It has to be really simple for me.
This is an olive emerger that I use now and then. Gink the wing and it floats well for a few casts but then needs drying out. I've had a few fish with it. Nae doot the experts will dae better.
Silk - Olive
Body and wing - Antron Body Wool.
Rib. Gold Wire.
After tying the body leave a loop at the head. Cut it and tease out for the wing. I also have a hare lug version using a stuff called Bug Yarn from Lureflash.
That's it.

Looks like a killer to me. I'll tie up a few and give them a go. I like things that are simple.
