Create a coordinated set of patterned planters by relief-spray-painting terra-cotta or other solid-colored vessels. First, take a piece of lace or crochet trim and wrap it around a porous pot, such as clay; secure it in place with tape. Spray clear polyurethane over the lace. The spray creates a subtle difference in color as it soaks into the pot. Let it dry thoroughly before removing the lace.
