I have just found the cutest printable Valentines ever! I found plenty others for the kids to cut out and take to their friends, but I have reserved these for myself!
By the way, printing Valentines (just do a search for free printable Valentines) is QUICK, CHEAP, and good cutting practice for preschoolers. They love it! My 2-year-old relished being allowed to cut his own. And it's okay that they don't look neat because, after all, he is only two!
