Thanks! We ordered both the custom postage stamp, vintage beach stamp and return address label from Zazzle.com I bought all the envelopes (A7 envelope, gold liner and petal envelopes) at the same paper store so I knew they'd match and be the right size. I used a double sided glue tape (similar to this: http://www.paper-source.com/cgi-bin/paper/item/Sticky-Tape-Runner/2903.016/496889.html) to glue the gold liners in to the envelopes. Super easy, just a little time consuming. I can't take credit for the postcard -- that was all my fiance -- he and a coworker designed them in photoshop and got them printed at a local print shop. (I bet Vistaprint would have been way cheaper than that place, oh well!). I think they borrowed a stamp brush from here: http://www.psd-dude.com/tutorials/resources/stamp-brushes-for-photoshop.aspx and then added the heart and date.
