Rayon Challis (pronounced sha-lee) is a lightweight, semi synthetic woven fabric. Often this apparel fabric is referred to simply as rayon. Rayon is a man-made fiber but is comprised of natural fibers. Thus, rayon challis is the perfect fabric for warm weather clothing. Rayon challis is 100% rayon.
Rayon Challis is soft to the touch and very drapey. It’s a bit softer than both voile and lawn, but with even more drape and pliability. Thus, it can be a slightly harder fabric to sew with.
If, like me, you have ever been a Target sundress aficionado, you likely have some rayon challis hanging in your closet. The fabric is often seen sewn up into sundresses and skirts produced by big box stores. Wrinkles fall out of rayon challis after just a few minutes of wear, so it’s ideal for travel clothing.
