Centura lists Bee Box Mosaics Light Grey in the Bee Box Mosaics range: a 11" x 12" mosaic. Floor and wall use are both covered, useful where a feature wall and the floor beneath it need to match exactly. It ships 20 pieces to a box, covering 19.66 sq ft, or 0.983 sq ft a piece. Mosaic sheets are mounted on mesh, so the pattern stays aligned while it is set and the sheet can be cut to fit an edge.
