Zen-It is a tied down caddis pattern originated by a tier out of Bend, Oregon specifically for the strain of Atlantic Salmon that used to be in Hosmer Lake. My brother found out about the fly in about 1964 and we have tied and used it with great success in Oregon, Washington, Idaho, Montana and Wyoming. Tie it in size 8-14 on a light dry hook, thin green body. palmered brown hackle, then clip the top of the hackle flat, then tie deer hair at both ends of hook. If you are interested-e-mail me your mailing address and I will send you a sample.
