These may be the only farolitos burning in London SW19 tonight. If we can't be in Northern New Mexico for Christmas, let's import what we can here. So the sandwich bags - of exactly the right height and thin heft - are from Kaune's food store in Santa Fe. The tea lights, admittedly, we bought down the hill in Waitrose. And the ballast? Inspiration struck around 3 p.m., and we went out and bought a bag of cat litter. Of course, the only cat litter on sale in Wimbledon Village at 3.30 p.m. on Christmas Eve is 99% dust free, "gold quality," lightly perfumed, and costs nine pounds fifty. But this is a small price to pay for having little lit lanterns lighting their golden way down the front steps to my parents' house.
