I recently saw a picture in a Kaisercraft magazine of a heart shaped card. I had a play around and worked out how to construct the card using the Hearts Collection Framelits. This is my card I made.
The DPS is from the "More Amore" and the "2013-14 In-colours" Paper Packs and the embellishments are from the "Artisan Embellishment Kit". The card folds down and fits in a 150cm x 150cm square envelope.
