Greeting Card App

Interested in Farsi typography I started making Happy Birthday cards. I intended to create different letterforms using essential characteristics of Farsi letters. Also, wanted to show the potential of Farsi letters to turn into various typefaces. Then I thought it might be a good idea to put them in an app so people can order them online, add notes, choose the type, and change the BG color!
