My oldest unquilted top was made in 1994. I made the top when I was packing to move here. The oldest project that I have never finished is 25 to 30 years old. I'm not even sure when I first started it. It was sometime between 1974 and 1983 when I started it. It will remain an UFO because I am no longer interested in hand appliqueing one single red print fabric on solid white cotton-polyester blend background. I think that project beats most current quilters' projects for UFO age.
