Well, thanks to you guys - our Lil' Happy Invisible Creature S.A.S.E. Club was a success. We are still counting envelopes, but it looks like we received 200+ submissions. We can honestly say that you guys made our trip to the post office something to actually look forward to (and subsequently brought smiles and fun comments from USPS employees - which usually isn't the norm), so our mission has officially been accomplished. Now it's time for us to return the favor. Since we received so many envelopes (and the shop has been busy), we're running a tad later than we had planned. But like we said when we launched this, have patience. It will arrive.
Since this was so fun, we'll be making this an annual tradition each summer. Thanks again, everyone.
