Someone (I'm so sorry, I don't remember who, and I didn't save it) on Every Day Matters blogged about a guy who was sending an "artful" envelope to anyone who requested one, so of course I did! The guy is Mark B. Hill, and here is his website,

in case you want to see some other examples (trust me, you do), and HERE is the envelope he sent me!
Coincidentally (and this is quite a coincidence considering I live in Southern California where it hardly ever rains), it arrived on a day when we were having a seasonally late drenching downpour! Thanks, Mark Hill! I'm working on something to send back to you, as I promised when I requested yours!
