This Tapestry Comb/Beater is suitable for small and medium sized tapestry weaving. It is made of solid brass and is 1-1/2 inches by 2-3/4 inches and is 1/8 inch thick. It has approximately 9 teeth per inch and is used for pressing weft yarns into place as the tapestry is woven. The large hole provides a comfortable grip and allows you to hang the tool on a ribbon/necklace. This tool is user friendly and works well with my 9 by 10 inch loom and my 12 inch square tapestry loom.
