Here's a nice website with some info for anyone wishing to try this. I was hunting for one on tying jigs. My last attempt at tying jigs was when I was 16. We tied a hook on our line squeezed a split shot over the eye of the hook, and wrapped the shank with his dads pipe cleaners. We thought we had some surefire fish killers,but I don't have to tell you how well they worked.
