I purchased an airbrush recently and I'm slowly getting the hang of using it on paper, fur, and fleece but, how do you make it so it won't wash off of a fursuit head? It says I need to heat set the fabric with the pain on it to keep it from washing off, but you cannot do that on a fursuit head, you'll ruin the fur.

So how do other suit makers who use an airbrush keep the paint from being washed off? Its a very cool tool, I love it and I'd really like to use it on my fursuit heads from now on, but I'm scared my clients will be out in the rain, or want to wash their heads and wash off and blur out all the markings.

So help? Anyone?
