A set of chipboard cards (a solid back plus an overlay with a window).
Use it as a flat card (glue the 2 pieces together after decorating) or paper-hinge the front like a book cover. Maybe add some adhesive foam dots for a little depth between the front and back... I'm sure you'll find your own uses.
Approx. 4" x 6"
One set (1 back and 1 laser-cut overlay)
This card is also included in The Snow Queen Kit; see all the other kit components available to buy separately.
