My invitations came with white envelopes that are the same size as something your bills would come in (Per customer service, I was expecting something narrower). They have the return address foil-stamped on the back in pink, but I'd like them to stand out a little and be a little fancier instead of getting lost in a stack of bills.
Any DIY suggestions? Things I have thought of:
-Put the matching foil stickers on the front-top-left where a return address sticker usually goes (since the return address is on the back) but is that even "legal" with the post office?
-Get some kind of glitter stamper design. With this I'm not sure a) if glitter is permissible in the post; b) where on the envelope a design could go, aesthetically and following with postal regulations.
I would love any thoughts, criticisms, and suggestions. Thank you!
