I finished up designing my STD and I plan on getting it printed at Vistaprint in a postcard. I am using a 4x6 postcard so that I am able to send it internationally (there are size requirements to send them internationally). The front part was easy and fun, but I had a bit of a challenge with the back part because there are so many USPS guidelines on where to place the text and graphics (and I've searched everywhere on Google images). I just want to make sure it passes muster because I would hate to have them mailed back to me. Has anyone gone through this before? Also, I left the address area blank rather than adding lines for the addresses. Is this okay as well?
