Talk about easy! For this card, I just grabbed one of our Whisper White note cards that come with envelopes, added a piece of designer paper leftover from last year's paper stack backed with coordinating Real Red card stock, punched out three hearts, and finished off by stamping, fussy cutting and attaching a panda from the Sale-a-Bration catalog. Note: the center heart is popped up with dimensionals as is the little Panda Bear. The heart on his envelope makes him perfect for a Valentine, but would also work for any kind of greeting to someone you care about.
We made this as a bonus card at my January stamp class. The Party Pandas stamp set is free with a $50 order.
Although the dsp I used on this card is retired, any design from the 12" x 12"Painted with Love Specialty Designer Series Paper (12 sheets, 145580, $13.00) would work well, too. You would just have to use one of the other colors (Calypso Coral, Melon Mambo, Powder Pink) in place of Real Red. My polka dot heaert was the reverse side of my design paper.
I also used the retired heart-shaped punch, but you can use the one of the Sweet & Sassy Framelits (15 dies, 141707, $35.00)
