Sand comes in sizes. Play sand from the hardware store is soft and fine. Beach sand is coarser and might have tiny shell shards (watch your fingers). For a glow-in-the-dark effect, mix in some glow powder from a craft store. For sparkle, dump in fine glitter until it looks like a unicorn sneezed on it.
Here’s a weird trick: bake your sand in the oven at 200°F for 20 minutes. This dries it out and kills any hitchhiking bacteria. Your paint won’t mold. And it won’t smell like a damp sock. You’re welcome.
How to paint with it (yes, it’s different)
Do not use a fancy brush. You will ruin it. The sand acts like a thousand tiny chisels. Use a cheap foam brush, a spatula, or your fingers (get messy, you’re an artist). Dab it on, don’t brush it back and forth. If you sweep, you’ll push the sand into a sad pile.
Thick layers look like stucco. Thin layers look like wrinkled skin. Both are beautiful in their own gritty way. Let each layer dry for at least an hour. If it cracks, that’s character, not failure. Old masters paid extra for that crackle effect.
