BurdaStyle’s guest columnist Erin Gilday goes into great detail over the art of cording in fashion that’s been around for centuries. I love this style detail that looks great on dresses.

Cording – cord wrapped in fabric that’s been cut on the bias – is an ancient embellishment that packs as much punch today as it did in the 1730’s or the 1940’s. Whether you use it to make appliqued motifs, corded pin tucks, frogs, spaghetti straps or piping, cording is one of the most versatile weapons in your sewing arsenal.
