Soutache is a charming little shop on 2125 North Damen Ave, Chicago, which specializes in embellishments: ribbons, buttons, feathers & flowers. They have also introduced ribbon embroidery classes so that students learn basic stitches in order to create charming keepsakes and gifts. I did find some purse accessories including feet at this shop.
