My son (Montanaboy} just started tying. He says he will only tie a few jigs that he knows will work (ha). When the creative juices start flowing, he will be tying all kinds of combinations.
i experiment with all kinds of material (the wife's yarn, trout-tying feathers, even some Arctic fox fur that I got from Skip). Result: Over a hundred jigs that have never been in the water. Lately, I have been using several previously untried jigs each time out. Some working very well, some probably just drawing a chuckle from any crappie that sees them.
