I've been working on the 12 x 12 x 12 series for nine years. It gives me time to create one 12" x 12" x 1" piece on board each month. It's a wonderful opportunity for me to experiment with an idea or technique or a combination of both. Some of the pieces over the months and years have been really good, and others not so much. The only rules I have are that I have make something in the given month, and I can't throw the work out, even if it's unsuccessful.
For my September piece, I'm considering using some pictures of a neighbor's white picket fence mostly buried in the snow. I'll start it on or after September first. Stay tuned.
