Step Two

Open the Mylar blanket package, unfold it fully, and get someone to help you. Spray a light coat of adhesive over the entire surface of one of the 2×6′ Coroplast sheets and, with your helper, stretch the Mylar sheet and lay it over the Coroplast. Smooth the Mylar onto the glued surface with a bunched-up towel. Use the remaining Mylar to repeat the process for your second 2×6′ piece of Coroplast.

Step Three

After the glue dries, trim away the excess Mylar with your craft knife. Next, cut one of your 2×6′ mirror sheets into three 2×2′ squares.
