Nice ties. I'm sure they will catch fish for you.
If you're tying chenille body jigs, you don't need to buy a bunch of thread. This is what you want:

Coats Transparent monofilament thread. Costs about $3 for 400 yards. Cheap and matches any color. Available at just about any craft store that sells sewing supplies. Comes in polyester and nylon (most stores I've found only carry the polyester but either should work.) It's all I use except when I'm tying thread necks or jigs for toothy fish.
Don't worry, catch crappie.
