I am working on one at the moment that a girlfriend gave me. These were her mothers and the fabric is definitely 30's and 40's. I pinned them to my unbleached muslin and am doing needle turned applique. The centers are already sewn to the plates. There is one cneter that was too far gone to use and I will have to make a replacement for it. It is a circhle but there are little ovals pieced within the circle. Kind of like robbing Peter to pay Paul only its a cirlce instead of a square. I have a little over half done.
