Set down newspaper or tarp to protect your work surface from paint, or place the wreath inside a cardboard box before painting. Spray-paint the wreath with the white paint to create a light background for your spooky bat's nest; black and gray bats will pop against the white surface. Set aside the wreath to dry while you create the bats.
Cut black and grey paper into squares using a crafts knife. We used 8-, 9-, and 10-inch squares to create bats of different sizes. Use the folding pattern available in the free download to turn each square into an adorable bat.
When the wreath is dry and the bats are all folded, glue the bats to the grapevine wreath. Place glue on the back of each bat and press lightly onto the wreath. Try to stagger the bats, as if they are taking flight from the wreath in many directions or swarming your front door. Once the glue dries, hang this outdoor Halloween decoration in time for trick-or-treating! To add an extra festive touch, attach one extra bat to the door, as if he were flying away from the wreath.
