You can contact Blue Ribbon Flies (www.blueribbonflies.com) the originator of this pattern. They may be willing to give it to you. If not, they'll sell you their pattern sheets from the year that contains this pattern (they used to call it Mayfly Cripple, then changed it to DOA Dun). The pattern sheets are cheap, and this shop consistently comes up with great new patterns. They publish each years new patterns in a littel flier, which, like I said, they'll sell you pretty cheap. They also have great materials and a wonderful shop in West Yellowstone. No, I don't own a piece of BRF, and I'm not related to the owners. But I have to say I look forward to getting their catalog every winter more than any other fly shop I know.
