Step 1: Cut boards
but any pressed (not corrugated) cardboard that's about 1/16" thick will do.
Step 2: Attach Hinges and Trim
Place the two pairs side-by-side, face down. Join two of the squares with a strip of tape.
Add a strip of tape to the outside edges of each square. Use a separate piece of tape for each square.
Step 3: Create Playing Surface
Trim the adhesive paper down to 7 1/4"x7 1/4", leaving 1/4" of white space on the outside edge of each square.
Peel off the backing of each sheet and apply to the board.
