Family owned and operated since 1971, Harrisville Designs PRO Loops in the Bright Line Black Pack are custom-sized for our 10-inch Potholder PRO Size Loom Kit (10-1/4-inch x 10-1/4-inch PRO Loom sold separately). This bag contains enough loops to make two 8-1/4-inch x 8-1/4-inch potholders using the Harrisville Designs sturdy, long lasting metal 10-inch Potholder (PRO Size) Loom Kit. Use these premium quality, custom made, 100% cotton loops to make potholders in a single color; or create multi-shaded designs by combining other Harrisville colors (sold separately). Hand weaving is a time-honored, educational, fun, and truly bonding activity for both kids and adults to do together. Children feel accomplished when they create beautiful, practical items they can use at home or give as gifts. Hand weaving, knitting and felting are wonderful intergenerational activities your whole family can share. At Harrisville Designs, we are exceptionally proud to preserve and share our New Hampshire tradition of handmade 100% cotton textiles produced exclusively in the USA.
