Glowing starburst motifs radiate in rays of yellow, lime green and deep red over a dark maroon ground, each star framed by diamond-shaped petals that fan outward. The bursts sit in a regular grid, with their centers aligned in rows and columns, so the diamond forms repeat in a steady, rhythmic lattice across the page.
