I saw this project on Martha Stewart while on maternity leave and knew I wanted to make it. The wooden box was at Joanne's for $3 and the wooden squares were less than that. So I am thinking it is about a $5 if you use old paper like I did or $7 if you need paper or ModgePodge.
I made wallet size copies of the photos from Walgreens. You end up with an extra set of pictures so you can make two games... maybe one for cousins.
We keep all of our scrapbooks in the front room and about twice a month we pile in there after dinner and look at all the memories, so this game will be added to the shelf. It really is perfect since our family lives so far away and Mike is the perfect age for simple games.
