Cut a 6" by 1'6" piece of plywood and draw out a setup of the mirrors on the wood like shown above. Make sure there is at least 1.5" on either side of your drawing. Make holes big enough for your dowels to fit into where you marked out spots for the mirrors. Cut out 1" by 1" mirrors from your mirror using a glass cutter. Cut your dowels into 2" pieces. Use hot glue to attach a dowel to the center of each mirror, put each of these into the already drilled holes in your plywood.
