I also can use the travel magnetic board as a dry erase board for when my little girl gets a little bit older.
Step 1: Magnet supplies
There were a ton to choose from...I didn't even buy 1/2 of the selection.
Step 2: Magnets
Step 3: Magnet board
My magnetic boards were 9 inches by 12 inches, so I cut 2 pieces of felt 9.5 inches by 12.5 inches. (I got the stiff felt because it was bigger, but I'm sure any kind would work that was the right size) These were to glue the boards on to.
I also cut 2 pieces of felt the same size (9.5 x 12.5) but cut out a smaller 8.5 x 11.5 square from the center. This left me two rectangular "borders" of felt. This was to put on top of the board to create a nice border around the edges.
