I spent yesterday preparing the substrates. I am using three gallery-wrapped canvases; the center one is 24" x 48", and there will be one on each side measuring 18" x 24", so this will be a horizontal installation measuring 7 feet long and 2 feet wide. I flipped the canvas over so the back is now what I call the front. I glued pieces of 1/4" birch plywood to the front of each canvas, using Liquid Nails, and then placed wood screws at each corner. I clamped it all together and left it overnight. Remember, I already have the mosaic done on mesh! so it should go quickly.
