I started by pulling out scraps of purple - velvets, satins, chiffons, cottons - then machine pieced the scraps together. Various circle shapes were stamped on the fabric using purple acrylic paints. It was then sandwiched with batting and backing and cut into six 4"x6" postcard size pieces and machine satin-stitched around the perimeter.
I had just enough hand-dyed fabric to back only five of the six postcards. The sixth card was backed with a commercially printed fabric.
