Here is the progress I've made on the embroidered piece of Frank's dinner corset. It's an overlay of netting, which as it turns out is
not easy to embroider on. I've tried a variety of stabilizers and metallic thread combinations. The flower (chrysanthemum?) has 9 petals, and my design was copied from the flower located on the center front of the corset, where the velvet ends and the chiffon top begins.
The Anal Retentive Costume List has some amazing photos of the corset for research.
