Bonjour & Hello!
Do what you love for someone you love. =)
Kudos to you for completing the game with a box! This is the original page where Josh first posted his box. He says that he glued it onto an old Cranium box if that helps.
I printed the box art that's been going around (created by Josh) and was planning on building a box but the chipboard I got was too narrow. The art is a square image that measures just shy of 12x12 and with the side flaps, I need a box that is 12x12x2.5. Is there a prebuilt box I can pick up somewhere that meets these specifications or does anyone have and idea where I could pick up chipboard that is 18x18"?
