So what is a floating frame, anyway? A floating frame is defined as an L-shape picture frame that attaches a single-layer piece of art from the back side of the frame so the art appears to be floating. This style of floater frame exposes the edges of the art without the need for glass or mats, and is ideal for canvas paintings and canvas board art. Additional types of float-mount framing include double-glass or acrylic picture frames, and top-mounted mats in a frame with spacers, however, floating frames are generally known to be the kind for canvas wall art.
