Along with my intense DIY invites for the wedding, I was given the idea to try custom stamps just for the outside envelope not necessarily for the RSVP envelope but I wasn't sure where to look. I tried zazzle and shutterfly and they seem to be more expensive than a regular stamp. I get they are custom but my step mother said they have them somewhere for the same price. She is looking into it but I wanted to know if anyone had any suggestions. I'd probably do something with our faces on it or the wedding date maybe.
