I've come up with this brilliant idea of how I want the invitations for my DH's party to look YET I haven't a clue as to how to execute it properly, so I'm coming to you for help.ok each of you know how a closed envelope looks, well my idea is to have all cornes of the envelope sealed with a sticker and then the guest would have to open the corners of the envelope (where it's held together with the sticker) to see the invitation that is inserted dead center of the envelope by placing the ends thru slits on the sides.(I HOPE THAT MADE SENSE CUZ IT WAS HARD AS HELL TO TYPE OUT...hahaha)my problem is I know there a word for the type of envelope I'm looking for and I know there's a word for the actual invitation part that is inside, so that's what I need help with so that I can go to a stationary store and talk intelligently to the staff when placing my order...any assistance you ladies can provide would be greatly appreciated!
