mondocherry.blogspot.com. They have an awesome site with lots and lots of things to look at and think about.
The background is done with a Martha Stewart corner punch and I embossed the background with an embossing folder.
The way I got the heart shape was to lay a heart die onto my background and then I placed the hearts inside where I wanted them to go, glued them down, and then removed the die. It was pretty easy to do and made a very pretty Valentines Day card.
