Here is an idea for a score keeper to use with your favorite game. All I did was take an old clip board and spray it with chalkboard paint. It is light weight, reusable, and can be used to score any game you chose.
This score board could be customized in many ways. Lines to separate the scores could be drawn in a contrasting color with paint or permanent markers. A card board drink coaster could be painted to make a miniature score board for the pub. A section of a favorite game table could be painted so you never lose the score board.
If you have any ideas on making a chalk scoreboard please share them in the comments.
