This little brush is made of slim metal tines that are bent at an angle. The original was created in the 1790s to change the nature of woven materials, threads and yarns. It serves the same purpose today. Use it to brush out yarn to create a fuzzy effect (yarn for Santa's beard). Or, use it to create a fuzzy effect in stitches already sewn in your embroidery - simply brush gently over the stitched area.
