To make this feltboard, you need 1 yard of felt, foam core board, and a hot glue gun and glue.
First, I laid the foam core board onto the felt and cut around it.
Then, I just glued the felt to the back of the foam core board using the hot glue. I put about a two inch strip of hot glue on at a time and pulled the felt onto it tightly. I thought about taking a picture of this process, but it was impossible since I don't have 3 hands :)
Here is our finished felt board. It turned out exactly as I envisioned it (that rarely happpens)!
I put a piece of sticky backed velcro on the back of the felt board and the wardrobe, and now we have an easily removeable felt board. E(1) and I have enjoyed using it during our morning "school" time.
