Hi there!! I have 2 wooden dog bone shapes of 1/4" pine craft board. Roughly 2 inches by 6 inches. I am trying to hinge them onto a 10" x 12" piece of 3/4" sanded plywood. I am trying to have 2 hinges on each bone. One on each end, for each bone. 4 total. I'm struggling with trying to find a hinge that allows the bones to sit flush on both sides against the plywood. Is there something I can cut out of the plywood?
