Is it still painting if you're using wax? I don't know... and I don't really care because I think the results are pretty awesome.
You will need:
- Sealing wax in multiple colors
- Lighter (yes, mine is shaped like a gun)
If you're lucky, the colors might melt together some and create a cool effect.
You can also tilt the canvas as you go, letting the wax run until it cools. I did mine in sort of a gradient, with the black concentrated in one corner and the gold concentrated in the other corner.
