I have an oil painting on flat canvas board to mount in a floater frame. The customer wants the painting to be flush with the top of the moulding which has a 1/2" flat top and is 1" deep (boxed effect). I often put stretched canvases in floaters, but how do I mount/attach a canvas board to the filler board and then the filler to the frame???
