Subtle windowpane checks lend a bit of pattern to this dark blue placemat from Chilewich. Each antimicrobial mat weaves PVC yarns treated with TerraStrand, a proprietary compound that contains vegetable compounds that replace petroleum-based plasticizers used to soften yarns. Ours exclusively, the tonal indigo placemat cleans up easily with just the wipe of a damp cloth and a quick towel dry.
