A quilled flower set in the middle of this would make a pretty ornament! Just thread a cord through one of the inside of the tubes and pull it through the top, for a hanger. I would make single layers, if I were making an ornament.
Make colorful and inexpensive trivets out of clothespins! Aren't these wooden clothespin trivets fun? Heat resistent glue and maybe a piece of wood or felt to help hold together more. Can be plain wood or painted
