Polyester is one of the most lamented quilting fabrics of the past, but like it or not, it is part of American quiltmaking tradition. It may not be as rare as the 18th century fabrics made of natural fibers, such as blue resist, cotton chintz, or calendered wool, but it is just as important in its own way. Polyester was widely available during the American quiltmaking revival of the 1970s. Millions of Americans learned to quilt with it, and they made remarkably vibrant, enduring objects.
