This card is approximately 4-1/4" x 5-1/2" when finished and features a pop-up design on the inside. The files come with the card base, the paper elements shown, the inside pop-up mat, and mats for the pop-up. All of the files are compatible with both the 8x12 and 12x12 mats.  You can see more on my blog: https://jamielanedesigns.blogspot.com/2018/12/pop-up-valentine-cards.html
