I made 30 of these Valentine Treat cards for my Granddaughter's 3rd grade class. I began with the red cardstock cut 3 1/2" x 3 1/2" and the patterned paper cut 3 3/8" x 3 3/8".
The red heart was cut out using the Recollections Scalloped Heart Punch then I punched out the center using the Heart Punch from Stampin Up which is the same size as the treat box.
These valentine treat boxes already have glue on the back so once filled with M&M's I just had to remove the protective strip, adhere to the center of the patterned paper, glued the red heart around the treat box and added a large bow to the top center of the card. I hope she and her class enjoy this little treat as much as I did making them.
