Lay mirror on a flat surface.
Starting with the larger sizes, position sand dollars on mirror. Layer on medium-size ones; then add accents and fill in holes with the smallest ones.
Carefully lift the base sand dollars slightly, and apply glue underneath to adhere them to mirror; continue adhering rest of sand dollars. (If you make a mistake in positioning, you can pry off the sand dollars and start again.) Let dry.
Assorted sand dollars of varying types and sizes (we used 2 large, 14 medium, and 41 small sand dollars)
