Cut 4 7½"x7½ squares from pressed cardboard. I used Bienfang illustration board
but any pressed (not corrugated) cardboard that's about 1/16" thick will do.
2. Add Forward-folding Hinges
Place two squares side-by-side, face up. Join the two squares with a strip of tape.
Duct tape works well. Repeat for the other pair of squares.
3. Add Backward-folding Hinge
Place the two pairs side-by-side, face down. Join two of the squares with a strip of tape.
4. Add Trim to Outside Edges
Add a strip of tape to the outside edges of each square. Use a separate piece of tape for each square.
5. Print Images
Print 4 7" x 7" images on adhesive paper, one for each quardrant of the game.
I used Avery full sheet labels for this.
6. Trim Images
Trim the adhesive paper down to 7¼"x7¼";, leaving ¼" of white space
on the outside edge of each square.
7. Add Images to Board
Peel off the backing of each sheet and apply to the board.
