Valentine bookmark craft kit from Kazsmom on Etsy. Looks like hearts laminated between two lamination sheets to me, with hole punched in the top for a ribbon. Could change up from hearts to Christmas trees, or Christmas star and such.
Valentine's Day Ideas: Sew or glue a bunch of little red buttons to form a heart on a piece of canvas. Add a cute bow and heart pendant and it would ultimately look like the cutest Valentine’s Day design fit for the love of your life.
