This is a printable template that comes as a PDF file and requires a printer along with manual cutting/scoring.

This Valentine Dutch Door Card is approximately 4-1/4" x 4-1/2" and features a half swinging front flap to give it a dutch door.  The file comes with the card base, three coordinating mats, and the decorative elements.  See more on my blog: https://jamielanedesigns.blogspot.com/2018/12/valentine-dutch-door-cards.html
