Hadrian's wall minimalist insert

If you are like me and only use one sheet from your game, you have a few centimeters free above the game sheets :)If you are like me and don't use only one sheet from your game, you have a few centimeters free above the game sheets :) 
I plastified my game sheets so i don't still have a block sheet nearly intact.
So I quickly designed a minimalist insert to keep the ressources and meeples easily on the table.
