A felt board can be both a pretty addition to a young child's room and an educational tool.

Remove the glass from the frame. Cut a piece of felt that is about 1 1/4 inches larger than the frame on all sides. Cut out the corners so the felt can be folded over the cardboard or mat board without becoming bulky.
Tape felt around the board, and place it into the frame, felt side out.
Add a second piece of cardboard over the back of the board, and secure it with a sheet of kraft paper and several lengths of packing tape.

Using felt for both the face of the board and the shapes that adhere to it, you can create an alphabet; use stencils or cookie cutters to trace out shapes, or make simple games like tic-tac-toe. Requiring only a few materials, the felt board is simple to make and can be hung on a bedroom wall or carried easily around the house.
