1. Lay a piece of heavy paper (it can be construction paper, cardstock or anything else that won’t warp when wet) on top of some newspaper. With a bottle of glue, “draw” whatever patterns you desire. You could write a message, or draw a nice Valentine heart, or just some Picasso-esque squiggles. Make sure the glue lines are pretty thick, but not big puddles.
    
2. Pour normal table salt over the wet glue. You’ll need a lot of salt for this. Make sure it gets onto all the glue. You can do this by tilting the paper after the salt is on it. Then shake off all the excess salt onto the newspaper or into a plastic container.
    
3. Using watercolors, paint the salt whatever colors you please. Make sure the paint is nice and watery so the paint brush doesn’t actually have to touch the salt that often. Don’t let it get too wet though, or it’ll wash the salt away. I recommend experimentation.

I love the intensity of the color you get with this technique, especially against a darker paper, and the tie-dye-like effect. Happy art making!
