Product notes: The sizes listed are for the canvases themselves. The frames add approximately 3/4" on all sides. For example, a 12"x12" canvas gallery wrap will be approximately 13 1/2" x 13 1/2" including the frame. The fully finished Canvas Gallery Wrap is mounted in the frame using a proprietary combination of tension and adhesive. We do not recommend removing your canvas from its frame, or attempting to put a different image within the frame. Framed Canvas Gallery Wraps come with pre-installed hanging hardware built into the frame, along with felt protective bumpers. The hanging hardware is placed at the top of the image. Material: 100% polyesterbase.
