I've been looking for a fun kid's calendar for ages with not luck. I had just about given up on ever having one until I came across this blog post. You don't need a laminator to make it but it will make the pieces more durable.
Here's our version.
It was an easy project using stuff I already had on hand. The pieces are kept in place with blu-tac. I put it up in the dining room and the kids enjoy updating it every morning.
