I like the idea of mixing the powder with specially crafted ink and just tattooing it on. You'd still have the image even after the Dust is gone, as that's what the ink it is mixed with is for, and we've already seen that you can literally just slam a crystal into something with Dust in it (Reese's Hoverboard) to recharge it.

It may seem like the 'easy' way of doing things, but it makes sense to me. It's meant to be an old technique. Why wouldn't they have figured out an easy way of doing it?
