Joann usually has what I need in muslin Right now I am using the Roc-Lon 120" wide bleached muslin. I buy it by the bolt for quilt backings or for the foundation on other blocks. Nice fabric. I also you the premium unbleached muslin from JAF. I try to stay away from most of their other fabrics. Prefer online fabric shops like fabric.com or Paducah. Our store is only curve side services right now and so there is nothing I really need.
