One of my fishing buddies was the R&D guy for McKenzie Flies in Eugene ( before the company went belly up). He spent a lot of time cruising fabric, hobby and craft stores looking for possible fly tying material. Every now and then he'd send me something he found and asked what I thought about using the material for fly tying. We'd tie some experimental patterns and give them a try. If the material worked, he'd contact the wholesaler of the material and the next thing you know, it was repackaged as fly tying material and sold at fly shops, at an increased price, of course. You guys may also want to look into Ryon embroidery threads and yarns for body material. I'm on a constant hunt for tying materials at fabric and craft stores... not to mention my brother's hobby shop. The first realistic yellow doll eyes (with a post) I found for my bass poppers were sold at craft stores.... once I published a few pattern articles that showed the use of the eyes, oddly enough, the eyes ended up sold in fly shops and I could no longer find them at craft stores. Much of the fly tying material we use did not start out as a product for tying flies.
