Clip Mirror is made of a prefabricated mirror sheet and metal binder clips.
Use 1/8” thick glass or acrylic mirror sheet, available at any glass store. They will cut it to any size you want. Cut a backing sheet of foamcore or corrugated cardboard of the same size as mirror. Connect the two sheets with a continuous row of Staples® Small Satin Silver Metal Binder Clips, 3/4" Size (available at Staples or at any large stationery store). Same clips can also be used for hanging your mirror on the wall.
