Colette is excited to be partnering with our BFF, Cotton+Steel for a fun and informative Substrate series. Devon, who you might recognize from our Sewalongs, will be teaching you all about how these fabrics are made and what’s so great about them over at the Cotton+Steel Blog. On the Colette side of things, we will be sharing our techniques for sewing these fabrics and which patterns work well with them and why.
Today’s featured substrate is rayon challis.
Rayon Challis is very lightweight plant based fabric that has a smooth, luxurious hand and slinky drape. The term Challis refers to the soft characteristic of the material, and it’s barely brushed surface texture. Some rayons have a bit of a sheen to them, but the plain weave of Cotton+Steel’s rayon challis is matte, with richly saturated colors. The wood pulp base of this semi-synthetic fabrics gives the fabric great breathability.
While the best thing about Rayon challis is it’s light and silky drape, it may cause some difficulty when sewing. Cotton+Steel rayon has a firmer hand and thickness than other rayons, making it easier to work with and less clingy when wearing. If you’ve been intimidated by working with rayon in the past, Cotton+Steel rayon is a great one to start with!

Cotton+Steel recommends that you dry clean their rayons. However, you can use your discretion and test wash a swatch to determine how you will care for your fabric. But, always be aware that results can vary.

Over-pressing can cause the fabric to shine. Press with a dry iron at a medium temperature. If you’d like to be extra cautious, use a press cloth.
Let the fabric rest and cool down for a couple of seconds before you remove it from your pressing surface. This will help the pressing or shaping stay in place.
Be extra mindful of your fabric’s grain line and use a rotary cutter for accuracy.
Try cutting rayon challis with a layer of tissue paper underneath the fabric. The tissue paper will prevent the fabric from shifting as you cut your pattern pieces.
Tailor Tacks, Tracing Wheel, and chalk marker all work well. Light colored rayon challis may be transparent. If your fabric is a slightly see-through, use lighter colors of chalk or tracing paper.
Fusible sheerweight interfacing works perfectly and will not effect the drape of the rayon. The more old-school sewist would recommend using silk organza.
Your thread weight should always match the weight of your fabric. For rayon challis, 40wt polyester or cotton work best.
70/10 HJ or HM, new needles always! Needles will snag your fabric if dull.
Bulky hems will weigh down your hem and might prevent the hem from flowing with the rest of your garment. A single-fold ⅝” blind hem will keep your garment’s hem light and airy.
The Myrtle is a perfect dress for Rayon Challis. For cowl necklines, bulky fabric can create a bit of bulge right above the bust. Rayon challis will lightly fold itself and create the perfect drape of a cowl.
The Myrtle has an easy elastic waist that lends it’s self to an airy, light fabric like a rayon challis. This substrate gives the skirt the freedom to sway and flatters anyone’s figure. A rayon Myrtle is a perfect blend of casual and classy and has the potential to be a tried-and-true dress in your wardrobe. Seriously, you could live in rayon challis Myrtles all summer long.
In a rayon, the Laurel will retain its shape while also adding a flirtatious swing to the dress. It is semi-fitted and really lets your Cotton+Steel prints shine without being bogged down by distracting details or shaping.
This Laurel is sewn up in a rayon from the Frock Collection by Sarah Watts for Cotton + Steel, in Gemstone Navy.
Rayon challis can be taken even one more step in a drapey direction by cutting it on the bias! One of our classics, Oolong, is cut on the bias and has a lovely ruched bust. If you’re worried about your rayon being transparent, the Oolong is lined and the bias allows for no zipper. Hallelujah!
- Staystitch immediately after cutting your pattern pieces. Even if the cut line just a bit curved, staystitch. This will help keep your seams from stretching and not matching up when sewing.
- Despite your best efforts at accurate cutting, seam lengths may differ when pinning. Sew with the longer seam on the bottom of the shorter seam, letting the feed dogs ease the longer side to match the shorter one.
- Use sharp, fine pins and pin horizontally to keep the fabric from shifting.
- Test your tensions before sewing up your garment. Delaney likes to hold her fabric from the front of the pressure foot and behind it, with a bit out tautness. This may help if your fabric seems to be puckering at your stitching line.
- Avoid hanging your pattern pieces between sewing sessions, rayon challis will most definitely stretch with gravity. Instead, store your pattern pieces flat or rolled up.
