Every year I have All Red Day - we dress all in red and I serve all red food. Just google for crafts and you'll find millions of those. One year I saved tissue boxes and we covered them with tissue paper and sitckers and used them for our Valentine's. Another year we made hanging folders. I make it different every year. We're making cookies this year and I've made up little loot bags to send home with some coloured rollon soap, stickers and candies. I always ask the parents to make up Valentines so they can put one in their friend's Valentine container.
