This article from Threads #175 (October/November 2014) by Daryl Lancaster will show you how to create your own trim styles.

The French have a wonderful word for applied decorative trimmings: passementerie. It encompasses many forms of needlework used to create beautiful flat braids and woven round cords for trimming upholstery, pillows, draperies, and-best of all-garments.

Weaving has endless trim design potential, and you can weave your own passementerie using a simple portable loom. With a small investment in equipment and some lovely threads, you can produce your own designer-style trim.

This article will teach you the basic weaving process, and introduce you to incorporating gimp thread or cord so you can design customized trim.
