Made with a combination of merino and wool stainless steel. You can change the length and the shape by pulling on the strings running from top to the bottom. Great to wear with boots. Great over leggings. It will look really cool with other stainless steel tops. The pattern is sold separately by the designer. Please download from cocoknits.com.
