DIY Felt Board

Some time ago, I got into felt activities with the kids.  I wanted to make a felt board because they are so expensive. 
Normally you would want to use something stronger, but there was a great deal at the craft store, so I bought thick foam board.  I used spray adhesive and covered the board with felt. Then  I reinforced it on the back side with duct tape. It works great for us. Easy and cheap!
