Candace from The Crafty Sisters created a large sunburst mirror to hang over her fireplace mantel. She used strips of wood and glued them around a mirror at varying lengths. I love the glaze treatment she used. It makes me think of the nautical driftwood found in beachy decor.
Her original inspiration came from the Sunburst Mirror from Ballard Designs (no longer available).
