Can do similar things with mylar tubing. I have tied some over beads to give a kinda nice body to them. The over all jig/fly sucks but the body is nice.

I think that you can extent the tubing over the jig head to cover the whole body with the stuff. Haven't tried yet but may have to just to see what it does and if it can be done.
The flashabou minnow body looks even easier to work with and might be much better than mylar for doing it.
I love taking my kids fishing, now if I could just manage to fish at the same time.
