Hip Hip Hooray! Have I told you how much I loooove kraft paper? If not, I'm telling you now. I used #10 kraft envelopes for my own Save The Dates last year. And I'm always trying to convince my clients to use kraft paper for their invitations and envelopes. Paper Source (one of my favorite stores ever) announced their new "Paper Bag" collection today. I'm so excited! Check it out at a store near you.
