I did these on Illustrator and printed and cut them myself. I also used gray A9 envelopes from papersource (where I got that neat embosser) which I lined with a photo of us from our engagement session with Punam Bean ( see here http://www.punambean.com/blog/?p=279). I was going to do custom stamps
but did not like the price so I was excited that the ‘love’ series stamp from the USPS worked well on the gray envelope. My last addition were the moo stickers which sealed the envelope in lieu of licking the glue – we did not want people to use a letter opener so you could see our lovely lining.
