I bought this fabric to cover insulation board to make a design wall for quilting. The fabric is thinner than flannel, but tightly woven and doesn't have a nap like flannel. However, on the finished design wall, quilt blocks adhere to it very well. Due to the thinness of the fabric, I covered the insulation board with quilt batting before covering it with the gridded flannel. I am happy with the finished project.
