[Sean]

lol not sure hwat its called. but martin hollinshead talked about a method of use permanent flying jesses, with very very small holes in the end, they attached is one largle or 2 small fishing swvils. that clip into the holes. can anyone explain this in more detail, and any pics if possible. i think his permanent jesses were buttoned, that went through the anklet, so how did these stay on?
