I'll get my flies in the mail today - sorry for the delay everybody.
Here's the recipe and some notes
Casual Dress:
Hook: Streamer hook, 4-10 (I used size 8)
Thread: Black
Tail: Short thick bunch of muskrat with guard hairs left in.
Body: Muskrat tied noodle style using dubbing loop. I removed guard hairs in body.
Collar: Muskrat with guard hairs
Head: Black ostrich herl
The Casual Dress is a Polly Rosborough pattern. Polly developed the pattern to “simulate nothing more than just food.” It's a bit of a monstrous looking pattern, I think it looks kind of like a small sculpin, or maybe a stonefly, dragonfly nymph or even a green drake nymph. But I guess it really doesn't matter what it imitates, as long as the fish think it looks like something to eat.
It's not a very easy pattern to tie at first – it definitely takes a little practice (I could probably use a little more! These flies a surely not one of my prettiest ties). The muskrat for the collar can be a little difficult to work with – you have to bear down on it pretty good to trap it and keep it from slipping out. I also found it very easy to tie the body too long and then not have enough room left for the collar and head, so be careful of that if you tie it. Also, the ostrich herl wanted to slide down the hook toward the eye, so I left a “tag” of thread just behind the ostrich before tying it in, and then wound this through the herl to hold it in place and reinforce it a bit.
