This Halloween Greeting Card is approximately 4-1/2" x 6-3/4" and comes with the card base, the detailed skull, and a mat. The card is compatible with the 8x12 and 12x12 mats. To assemble, cut the card base, skull, and the mat. Ink the detailed skull and then adhere the mat to the inside for writing. Carefully fold on the score line and embellish as desired!
