This is an unusual quilted cotton fabric. It has two layers. The top layer is a pieced fabric made up of multiple blue and white fabrics. The bottom layer is a plain muted navy. The layers have been quilted together with blue and white yarn, and there is and there is a catch stitch on the edges. It looks like a quilt without batting, but it does appear to be a textile which came off a roll this way.
This fabric is perfect for a Grainline Tamarack Jacket or robe.
