You’ll find silk dupioni readily available in local fabric shops and from online retailers such as fabric.com. This type of silk simply begs to be embroidered. Two of the nine wraps in my Wrapped in Embroidery book are trimmed with embroidered silk dupioni. The sheen, durability, & versatility of this fabric set it apart from many other fabrics. I prefer to wash mine before using it for smaller projects. A “recipe” for my particular method of pre-treating silk dupioni is part of a bonus on the CD included with the book.
This is something anyone can learn to do, and another form of free-motion embellishment for fashionable garments.
