Elements that touch the right edge resume from the left edge, elements at the top resume from the bottom, like one continuous pattern that tiles infinitely with no visible seams. Consistent intricate motif density across the entire tile including all four edges. Archival quality designer wallcovering, hand-engraved feel, museum-grade traditional damask/chinoiserie/toile aesthetic.`;
