This is another trick I have up my sleeves for the road trip. It is a 3-ring notebook that I've enchanced. First I have glued felt on the inside front cover. On the back inside cover I glued a piece of 8 1/2 x 11 cardstock that I first painted with magnetic paint found at most craft stores. Then I painted it with spray paint chalk.
I put some paper in the notebook for drawing, and also a pencil pocket to hold all the supplies such as chalk, crayons, felt, magnets, and eraser for the chalk board.
A fun thing you can do to personalize it is to print up some cool sayings or pictures and stick it to a magnet sheet. This way you can have your own words, pictures, or whatever you want. It is a great way to make it a little more educational.
To help secure the felt I put a border of clear packing tape around it. I also added a foam border, that I glued on, to the magnetic chalk board to avoid the paper from getting torn. I'm working on a better system for this project, but for now this works okay. It will last awhile and will definitely occupy the kids for some time.
