RCream,

Dick Talleur gives some instructions on making substitute JC feathers out of Guinea hen in his book on salmon flies. Somewhere on the web I saw some reasionable substitutes that looked like they were made with fabric paint. JC feathers were generally used to imitate eyes on baitfish patterns from an era before we had synthetic materials. If you are just interested in catching fish, you could forgoe the JC and just use a stick on eye. I think if you look around the web, you might be surprised to find some better deals on lesser grade JC necks but who knows if they are legal Good luck
