Trace the shape on the non-shiny side of the freezer paper. Leave enough space between them so you can cut them apart.
Iron the traced shapes onto felt. Cut out the pieces and peel off the paper.
Using skewer, paint tiny faces on the shapes. Make black dots for the eyes, pink dots for the cheeks, and a black U shape for the mouth.
Wrap the elastic around the book you plan on using your book band on and then add about 1 inch. Cut the elastic, and then tie the ends together with a knot.
Now attach the rainbow shapes with the help of glue. Give the glue plenty of time to dry.
