Arrange the folds so the section with the oval stands up like a tent in the center. This piece will become the outside cover of the card. Fold this piece in half lengthwise Cut two equally sized hearts from colored paper. Make sure the hearts are small enough to fit within the oval cutout. If the Ellison machine and heart die cut are not available, cut out two hearts with scissors.
Any shape can take the place of the heart cutouts.
Measure the thread so that the heart dangles in the center of the oval, leaving enough thread to tape the other end of the thread to the outer edge of the oval inside on the upper flat section. Sandwich the rest of the thread between the white and black panels when fastened. The black outer card should frame the white inside. Embellish with photographs and stickers if desired. Unfold the paper envelope and use it as a template.
