DIY: European Village Advent Calendar

I've been busy, busy, busy getting my Etsy shop ready for the holidays. I've had so much fun making cards and ornaments, that even if they don't sell, I won't care. The process alone is worth it! 
I just uploaded my very first digital download to the store. It's this adorable European Village Advent Calendar. It was inspired by buildings in Amsterdam and various other European architecture, like this Greek Revival country house somewhere in England or France. The "rough draft" was an advent calendar I hand-drew for my niece. I even made all the envelopes by hand. It went together in about a day, so I thought, why not draw some to reproduce!
 The final product (thanks in large part to my step-mom who's a graphic designer) is a printable PDF file that features envelope templates with 6 different hand-drawn buildings. As a special treat for my readers, I made a coupon for 20% off your purchase of the file! Use coupon code "DIY20" at check out.
 P.S. A little secret: that code will work on anything in my shop over $5 ;)♠
