You will need two strips of felt(for the bookmark).
Sketch and cut out a template.Then cut out that felt shape.Sew that onto one of the bookmark strips.
Cut and glue any extra shapes(like the eyes..)
For the mouth I used paint.
Cut a strip of cardboard(like from a cereal box)..it will need to be slightly smaller than the felt strips.Put it in between the two felt strips and sew all around.
You can also add a ribbon on top of the bookmark(I sewn a cute little pompom on the ribbon as well!)
