For a new take on holiday greenery, make a wreath of cactus pads. Fasten a wreath hanger or hook to the back of a straw wreath base. Then, using canning tongs to handle the prickly pear cactus pads (8 to 10 should suffice), attach them to the base with wood florist's picks, leaving an opening at the top for the fan palms and desert rose. Arrange the fan palms, glue the rose in place, then glue the whole arrangement to the base. Spray the wreath with clear polyurethane.
