They are looking pretty good. Look around in this jig making forum, there are lots of everyday materials you can use to get bye with.

I'd say always try to use as little thread as you can... less thread, less chance for things to move on ya and unravel once they get wet. Once you get some chenille or other body material, you will find you just don't need all the thread. Put a solid base and then body material on top. That's my preference anyway.

Those look much better than the first few I made!!!!!!!!!!
Keep it up!
