Keep in mind that it's easy to turn any stamped image into a valentine by using the traditional heart shape to stamp on. For all of you cat lovers, this clear set from Penny Black can cover lots of occasions. Priced at $16.95. Paper flowers and Bling have added the finishing touch.
There are so many Heart Shaped punches on the market. You can always make a quick card by punching some out of printed paper or different colours of card and then adhering them in a 'tumbling' pattern across a card face.
I used an already distressed Labels #1 cutout from my scrap drawer. The small envelope punch gives the hearts a starting point to tumble out of. The 'Be Mine Valentine' is from Impression Obsession, priced at $6.25. Don't be afraid to use non-traditional colours as shown in Earthtones below.
