Photographer and artist Julia Parris loves snail mail, and has been sending letters to friends around the world for as long as she can remember. In 2011 she started what would become known as the Handmade Valentine Exchange. At the time, Julia was making and sending valentines to a handful of friends around the globe, but the next year she invited the public to join and it doubled in size. Last year participation grew to include over 2000 people from as far as Germany, Spain, France, UK, Russia, Australia, Costa Rica and US.  

Sign up today to make and send 10 valentines to strangers around the world. In the meantime, you can follow Julia on Twitter for updates.
