I have seen this idea before to make an altoids tin into a tic tac toe game but this when I saw the idea I followed through and made it.
the lid in shades of pink and purple
the inside the playing pieces have small magnets on them
and I used some clear mac tac to hold the game board down
another idea I have seen online, melt crayons down to make
your own. My crayons turned out all right
