I have done it a couple times with mixed success but was wondering if anyone else has ever done it?

Basically you take the fins and skin of the fish and dry it to a leathery texture that can then be used to tie in on jigs and flies. It has a natural scent obviously and should be really good for fishing for crappie and gill with jigs to add that natural scent. Might even try it with minnows for an even more natural predator response. I have always used the fins of Rainbow trout to make mine but any fish is supposed to work. Even caught a couple trout on it putting a piece of it on a spinner and a small plug as well as just a small hook and just the fish skin.
