In mid-September my husband agreed to help me build a hut on our patio to prepare for the Jewish holiday of Sukkot, which celebrates the ancient Hebrews' sojourn through the desert after they escaped Egypt. Observant Jews build a sukkah, a temporary dwelling that symbolizes that journey. I drew some rough sketches and my husband ran down to Home Depot to buy lumber. "Do you think it will work?" I asked as I described my plan for the simple frame, using my arms -- fingers to elbow to make a 90-degree angle -- to illustrate.
