I guess it seems obvious to some, but at the time I thought of it, I assumed making holiday greeting cards out of LEGO elements was unique. In the end, I sent around a few dozen holiday cards. I used a white 16 x 16 baseplate and then created one of two designs: either a Chistmas tree or holly. I then wrote a message on the back using a silver-inked Sharpie. Recipients have been for the most part happy.
