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.
Just because you aren't given the credit and haven't been recognised for your work doesn't mean you have to give up or stop. You don't always need credit, other people do not always have to know what you are capable of doing as long as you do.
