They are a little like this.

My thought was sometimes people catch crappie when fishing for bass... so why not shrink a bass bait?
So I wanted a bass "jig" the first one had longer "back skirt" then I thought if I trimmed it back it might look like a fat shad... and wiggle just enough to have a crappie thump it... now if I can just find the fish!
