Before you rake them all away, pick up the prettiest leaves for a fluttering mobile. Collect foliage with intact stems and press in a heavy book for a few days. Wrap twine or ribbon around an 18-inch embroidery hoop; secure ends with hot glue. Tie eight 3-foot-long waxed strings at even intervals around it, attaching pinecones at the bottoms as weights. Knot the string around each leaf's stem, spacing randomly. Secure hoop to a ceiling hook using twine. Click through for more easy Halloween crafts for your home.
