Silk charmeuse sash belt measuring 71.5" (1.8 m) long by 2.5" (63 mm) wide with angled ends and edgestitching.
This sash belt also works as a long scarf, especially if you make it wider, like this 5.5" wide Banana Republic scarf, this 9" wide Karen Zambos Vintage Couture scarf, or this 5" wide Porter Grey scarf. Some, like the Karen Zambos scarf and this J.Crew silk twill sash belt, are topstitched. They are generally about 2 yds (1.8 m) long.
Materials: Silk twill and silk charmeuse are common fabrics to use, but any non-sheer woven fabric would work. Heavier weight fabrics would work best for use as a belt; lighter weight fabrics should be used if you want it to double as a scarf.
- Cut a strip of fabric about 2 yds (1.8 m) long as shown in Diagram 1. To determine how wide the strip needs to be, multiply your desired finished belt/scarf width by two and add 0.5" (13 mm).
- Fold the fabric strip in half lengthwise with right sides together and cut the ends at an angle, as shown in Diagram 2.
- With a 0.25" (6 mm) seam allowance, sew the raw edges together along both angled ends and along the length of the fabric, leaving an opening of about 4" (10 cm), as shown in Diagram 3.
- Trim the seam allowances at each corner, turn the sash right side out, and press.
- Finish by either (a) slipstitching the opening closed or (b) topstitching close to edge along all four sides of the sash.
Note: Alternatively, you can cut the fabric on the bias. With 44" (1.1 m) wide fabric, you can make a bias sash about 60" (1.5 m) long before having to add a seam.
