Here's an easy way to give new life to old terra-cotta pots you have around the shed: Paint them to create coordinating stripes. Using masking tape in various widths, mark a simple striped design on the pot. In a well-ventilated area, spray the exterior and the rim (and any accompanying saucers) with weatherproof spray paint; let dry completely. Peel off tape.
