At The Bench - Warmwater Fly Tyer - by Ward Bean

I knew I had seen it somewhere. It is supposed to be used for deerhair bugs but it ought to go thru other materials such as used for bodies. You stick rubber leg in loop push needle and connected loop thru. Do not pull on loop itself wait until rubber is sticking out far side and pull gently on it. I would then drop a dab of glue on leg and center it on bug.
