Wax It

Is great for painting on with either a small brush or a sculpting tool to harden the wool and/or give texture.

First melt the wax in a wax burner (eg, a burner for candle melts), then apply to the area you want to harden eg. feet or beak, you can then rub it smooth once it had cooled and hardened a little, or use a scultping tool to add texture.

I have even dipped the wool into the wax, waited until it has cooled to touch, then squished it with my fingers, it becomes a bit like a clay that you can shape (this does take a bit of practice).
