If writing a v-day card is not your thing, express it your feelings through a photo message! This is a cute DIY flipbook that requires little resource to put together.
All you need to do is setup a camera on a tripod and take photos in continuous mode. (Skip the tripod, if you have a friend or sibling helping you with the photos.) Then print out the photos, arrange it in your desire order and hold it together with a large paper clip.
