My ironing board. I got it from an elderly seamstress from whom I rented my very first studio in 1978. She was so wonderfully crochety, and had been sewing costumes for the stars since the 1940s. The ironing board is huge, and has a cast iron base, so it never tips over. It has been my constant companion in every house, studio, or sewing room I have tossed together. It has about 20 layers of flannel on it, each layer covering the previous and held on with elastic and safety pins. And it has a million and one uses - David Emerson used it to hold his piano at our wedding party! I look forward to having his do that again soon.
