As we did last year with our Dr Who Valentines (page 1 & page 2). We made up some Mario Bros. Valentines. We usually cut these out and then put them on a bag of microwave popcorn. Easy, everyone can use it, and fairly cute. If you want to use them go for it, click on the image and it will take you to my flickr site. Then you click on the "All Sizes" tab, and go to original size. Save it and print it. It should be about the size of a piece of paper. I used free desktop wallpapers to make them. Some of the sayings are awful! A couple we certainly won't be using for school, but my husband thought it was funny. Anyway, enjoy!
