I ordered some of our invitations a couple weeks ago and they have arrived! (We're getting them from Vistaprint and I have LivingSocial/Groupon deals that expire in December that I'm using for them, so we ordered early.) They are BEAUTIFUL! I'm so excited to have them here in my hands! Only one problem: the envelopes that they sent with the invitations are half the width. So now I have to find new envelopes for the invitiations, as well as pocket folds, which is proving incredibly difficult (and expensive). There seem to be NO 6x9 pocket folds that don't cost an arm and a leg.
If anyone has any helpful hints, please share!!
