I designed this picture in Pages for a Valentine's project. You can draw one like this with just the tools provided in iWork Pages and transfer it to electronic and printed documents —cards, posters, letters, as well as putting it on button-badges, t-shirts and mugs.
Follow the Valentine's tag to see how to make one like this and other posts related to St.Valentine's projects.
