Traditional diamond twill is reimagined as a blue-toned mosaic in this beautiful mat that dresses up indoor or outdoor spaces. Signature bi-color yarns weave a complex lattice composed of uniquely woven diamonds. Each mat is woven of PVC yarns treated with TerraStrand, Chilewich's proprietary compound that's phthalate-free and contains renewable vegetable compounds that replace petroleum-based plasticizers used to soften yarns.
