Use vinyl letter stickers to spell out a name or phrase on a blank canvas.
Working quickly, coat the entire canvas with Mod Podge using a paint brush.
While the Mod Podge is still wet, pour salt over the entire canvas.
Allow the Mod Podge to fully dry. Tilt the canvas over a garbage can (or over a baking sheet so you can reuse the salt) and very gently shake off the excess salt. Apply the watercolor paint to the salt.
Paint over the salt and letters until the entire canvas is covered.
Allow the paint to dry, then carefully peel off the stickers.
