A friend of mine is designing our invitations. There are two types that I am looking at a 5x7 or a seal and send (doesn't have an envelope). What places have people used to print their own invites? Has anyone every printed the seal and send and is so where? Did you buy your own paper or use what they had? Has anyone ever upload their invite to the Staples wedding invitation site and printed through that? Wondering about the quality.
