I went to the Fabric store and they have a section for curtains, chairs, furniture. They sell left over materials...3 1/2 yards for 3.99 a yard...Awesome 100 percent cotton thick weave material...I used it for the back of this one and other one that I made last week. I washed and dried...they look wonderful and feel great! I would recommend using that material for the backing of any quilt.
