Viscose jersey scarf with raw edges, measuring 2.5 yds (2.3 m) by 18" (46 cm).
Perfect for a long strip of leftover jersey fabric. I was inspired by the American Apparel jersey scarf which is as basic as it gets (just a rectangle of raw-edged fabric), but seems to be pretty popular for being so soft, versatile and portable (read what Mighty Goods had to say about it). All you'll need to make your own jersey scarf is 2-2.5 yds (1.8-2.3 m) of a soft jersey knit fabric. Cut the fabric as shown in Diagram 1.
You can pick a slightly sheer cotton jersey like the American Apparel scarf (which is 93" long by 16" wide). You can also try rayon jersey like this narrow Banana Republic metallic scarf (80" by 7") or this Nordstrom scarf (80" by 18"). Make sure that the wrong side of the fabric looks fairly nice because both sides of the fabric might show when you are wearing the scarf. After you cut your fabric, just leave the edges raw; the edges of many jersey fabrics curl up naturally.
