Sometimes you don't need a jacket, but want to have warm arms and a warm back. Shrugs are perfect for this.
One size fits most - length approx. 44“ (112 cm) from cuff to cuff and 26“ (66 cm) wide, slightly stretched.
If you need it a bit longer, or shorter, just add or leave a few pattern repeats.
You can use almost any worsted yarn. Gauge is for drop stitch pattern.
