I have a 8 x 10 canvas panel/ board that has an 5 5/16 x 8 7/8 image that is not set in the middle of the panel. As a canvas panel, I know it does not require glass. It had previously been framed by the artist with mats & without glass, I need not detail how that survived. i'd like to use a hand wrapped 2" maybe 3" liner & fillet with a frame, but I am stumped on how to mount it the way it is.
