MZA: Pre-Paid Envelope

Send 1 partner a letter (at least two full pages) in a pre-paid envelope - the kind where the post office prints a nice mark on the envelope specifying a certain amount of postage is already included. Vintage would be nice, although it is likely to require that you add extra postage.

The sign-up deadline is a month out to give you time to check your post office for pre-paid envelopes, or to find some on eBay (or where-ever). Senders choice, so you can write your letter in advance if you'd like.

That's it. Keeping it simple. It's my first time creating an MZA swap, so sorry if I'm missing any of the criteria you have come to expect.
