Jute is a highly sustainable crop with with well-insulating properties. These pot and pan holders are made with the scraps from jute/organic cotton bags and are completely compostable when you're eventually ready for new ones . The 8"x8" square potholders double as trivets, the shorter 4" - 5 ½" x 2 ½" pockets let you hold pot handles, and the long 2 ¼" x 5¾" pocket goes over skillet handles.
