Two 5-inch squares of flannel
One 5-inch square of felt
Cut out two 5-inch squares of flannel and one 5-inch square of felt.
Stack the fabric with the felt in the middle and the two pieces of flannel on the outside.
Using a glue gun, glue the three pieces together (or if you’re sew savvy, you can use a sewing machine).
Trim off any extra fabric.
