The Yellow Iris is the result of a concept I had to create a married wing wet fly using predominantly yellow and blue. It was created an April 2010. Here is the recipe:
Thread: White Danville Flymaster 6/0, black for head.
Hook: Standard wet fly hook
Tag: Yellow floss
Tail: Black duck quill sections, paired
Rib: Flat gold tinsel
Body: Dark blue floss
Wing: Yellow with a narrow stripe of dark blue – married
Head: Grif’s Thin cement, followed by several coats of Grif’s Thick, then one finish coat of black Pro Lak. All of these are lacquer base head cements, which is convenient.
Update February 2012: I just recently found out that Grif’s has discontinued the manufacture of their head cements. I managed to pick up a few bottles, but it’s of no consequence to me anyway, I like the thin cement as an all-purpose cement for all my tying, but for finishing flies I have another brand of high gloss clear cement that does not discolor.
