After much hair-pulling and trying to figure out how to make perforations for artistamps, I realized I could simply make faux aerogrammes instead. Either a real stamp goes beside the printed Cinderella and it goes through the regular post, or I do a fantasy rubber-stamped cancellation, pop the aerogramme in a larger envelope, and mail it that way. #MailArt #CinderellaStamps #FantasyArt #FauxPostage #Postoid #ArtistStamps
