Clamshells give a store-bought wreath nautical personality. Wrap a 14-inch wreath in 1⁄2-inch neutral-hue grosgrain ribbon. Attach the shells with hot glue, placing some end-to-end as if the clams are open. A knot of gauzy burlap creates a textural hanger. Matthew’s Secrets Display the wreath as part of a sea-inspired composition with spiky coral, sea oats, and stones.
