To make the pumpkin-and-gourd wreath, first cover a 20-inch foam form with sheet moss, using a glue gun to hold the moss in place. Loop a 3-inch-wide burlap ribbon over the wreath to create a hanger long enough so it can reach the top of the door and allow the wreath to hang at eye level. Insert wooden florist picks into the bottoms of pumpkins and gourds, and hot-glue the connection to secure. Once the glue has cooled, stick pumpkins and gourds into the wreath. Fill in with more moss, using a glue gun. To hang the wreath, secure the burlap ribbon with an upholstery tack hammered into the top edge of the door.
