another thing you can use to practice on is some old lures that you have not used because of chipped paint, hook rash, or whatever reason. I personally do mostly re-paints on walmart bargain box lures i can grab for a buck or two, i hit garage sales for lures real cheap and you can find alot of real good lures there at times, or order some unpainted blanks. the paint will not act the same shooting onto a paper towel roll as it would a plastic or wood lure. i will post some pics soon of some of the repaints i do. i dont sell baits i only do them for my personal use so i don't go into great detail, but they always seem to catch fish.
