Cut out squares of fabric. You can make two squares from each pattern if you are making a memory match type game or cut out lots of squares from each pattern if you are doing an organizing type activity.
As a side note, little ones love playing with the fabric scraps. Its a great QUIET activity.
When the squares are dry, trim the fabric so it matches up with the felt.
*While I used spray adhesive for this project, next time I will probably try a glue gun. The spray adhesive was pretty strong smelling, and it kind of lingered on the squares. If you have kids sensitive to chemicals definitely use a glue gun.
