This sunflower platter cookie cutter works along with a center 3.5" circle cookie cutter. You can purchase both cookie cutters together, or as a single piece without the circle cutter.
(This is the same circle cutter used in this Snowflake set, Spiral Platter, and Floral Wreath.)
When arranged as a large sunflower, as shown in the example picture, the platter measures 12 inches in diameter.
