"Waves" is a design created by artists who live with multiple sclerosis (MS). Each one has donated their heart and art to Our Heart Greeting, to take action in the search for a cure. To raise awareness for MS, a chronic progressive disease of the central nervous system, we're encouraging people to mail postcards! Postcards have a message that can be seen by each person that passes it, and they are fun to receive, and they oftentimes get tacked up on a fridge or bulletin board. Postcards are perfect!
