A little late, and not quite what I was planning on, but I did manage to finish a 2013 calendar! I have been working on some floral illustrations for my 2014 card line and thought they were perfect for this little wall calendar. They are 5.75 x 8" and ready to hang with white/gold twine. They also come in two colors:
Neon pink and minty green inks on French's Paper Co. Pure White - available here.
Blank ink on recycled kraft chipboard - available here.
