Cut the Painted With Love Designer Series Paper 2.5 x 4.5 (the same size as the card front)
Use dies from the Sweet & Sassy Framelits set that coordinate with the images from the Heart Happiness stamp set to make a cut out in the DSP.
Attach the DSP to the card front with Snail
Stamp the image through the opening with coordinating ink either Berry Burst or Sweet Sugarplum
I also added a row of hearts on the inside bottom of the card and the outside bottom front of the envelope using the small heart border stamp and Berry Burst ink pad.
(The hearts that were cut out I used to make another card you can find here.
