I'm sharing a new card kit today: Anna Griffin's Fantastic Flips Card kit. These are great window cards! I like to add a bit of paper on the inside to reinforce the small trim cut out around the right side of the window. (See the dark pink paper in the photo below). I just use my scraps and the die that came with the kit.
