Pros
- The cards are bright and colorful.
- A math tidbit is shared with at least two people: the sender and the recipient.
- I'm the only person I know who writes postcards.
My real goal is to share something that I love (math) in a way that many people would appreciate. I tried to turn the geometric shapes into cool designs and to add interesting flavor text. Is printed form the way to share these ideas? Would another format be more appealing? Thanks for your thoughts.
