I did these! Check out my recent thread of DIY invites and wedding stuff. My only warning to everyone is to make sure you either use sticky paper or use ridiculous amount of glue if you end up using regular paper. We used regular paper and even though I loved them, I started to put a sticker with the return address under them because I think the machine might have ripped some of them off (we got word that people weren''t getting them so sad)
Point is: They are gorgeous, but definitely use the stickiest of sticker paper!!!
