We transferred the measurements to the foam board and made the cuts. (I’m giving the Reader’s Digest version here due to space), then we put the boards together. Details here: http://www.underatexassky.com/cornice-boards-from-foam-board
Here are the boards completed. We firmed the connections up using toothpicks if you can imagine that.
Cover the board with batting using a staple gun. I didn’t want a heavily padded board so we went with a thin batting. Then next came the fabric. Now understand I was helping!!! But someone had to take the pictures.
These boards are so light- they were a cinch to handle. He placed them on the brackets, then secured the brackets to the inside top foam board to make it really secure.
