For a simple and easy-to-make holiday wreath, try this idea for an all-natural Christmas decoration. Lay a 10-inch plastic-foam flat wreath form on a protected surface, gather about 100 faux or real acorn tops and sort by size. Hot-glue the acorn tops to the wreath form, using the larger ones first and filling in the gaps with the smaller ones; let dry. Hot-glue a faux bird to the inner side of the wreath. Tie a twine bow and glue at the top of the wreath.
