Send one piece of postal themed mail in envelope with a flat surprise to your partner

Ideas: decorate using vintage postage, faux postage, postage-themed Washi, representations of Mr. Zip, letters, pens, whatever you can think of!

Flat surprise may or may not be postal-themed - ideas: blank postcards, notecards, Washi samples, bookmarks

Please include a note that is more than just the swap name & your name (but do include that too!)
