I just received a copy of Quilt World, July-August 1976. In reading the mag...I found references to nylon quilts. One person was asking for nylons to complete a quilt. Does anyone know what is a "Nylon Quilt" and what did these look like? On page 37, a quilter writes "The picture shows me with my first nylon stocking quilt to my right and above, then two baby quilts. ..." I can't tell what the quilts are. Sounds interesting.....and did these quilts last through the years of use?
