What a nifty idea! if you want creative envelopes, go to Maps, map the route from your letter to the other person's mailbox. Print them up, fold them into 8 by 11 envelopes (or smaller if you are sending cards). This would be cool for pen pals
Great idea as the kids wait for their turn to open their gift! - "Color Me" Interactive Gift Wrap for Kids - wrap a gift with plain white paper, and attach crayons instead of a bow. Stamp the words color me, and let your kid decorate their own gift.
