Barbara: Here are some terrific ideas!
Hi Barbara. I'm Cindy. You will need 4 pieces of wood trim. Cut each end of the wood with 45 degree angles. The store you purchase the trim from, may be able to make these cuts for you. (Usually at no charge.) Arrange them into the shape you want and glue them together using wood glue. You can purchase a frame hanging kit so that you can hang it. Good luck Barbara.
No power tools required! Have fun :)
