Outdoor placemats define seating arrangements, the separation of utensils, and protect the furniture from spills and condensation. When looking for a set of placemats, be sure to think about the colors, design, and purpose these placemats will bring to the backyard. Traditional rectangular placemats are nice but try an out-of-the-box circle shape for a fun switch! These round place settings come in a set of 6 and add a colorful, decorative element to the dining experience.
