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
Napkin as bow tie. How cute would this be for a wedding - especially if you did place card seating! turn it the other way, and tuck in a flower or tie it with bow.if you tie it higher, it might look like a dress!
