These are mitered but you could use simple slats to form a frame by measuring one side at a time until you have four pieces that make a frame. You leave area in the back so you can put all the pats to that game in a large zippered bag. Take the game board down when you want to play it with family and friends and simply lay the frame on the table after you get the pieces for the game out. When you are done put pieces back in bag and hang on the wall. Simple and really cool.
