I attached my white die cut from Die'sire with my felicitation words just over the edge of my red folded base card.
Next I folded a large piece of white cardstock in accordion style and attached it to the front of my card with on each part a cake, some party elements and red colored corner stickers.
The images of the cakes are from an old decoupage sheet from Picturel ( Kars and Co 11745/053 cut by hand into several layers and mad 3D.
The accordion part of my card is held closed with two red star brads.
