As I remember the 70's and sewing, there just wasn't much fabric that didn't have polyester in it! My g-ma embroidered some lovely squares of lilacs to be used in a quilt in the early 1950's but died before she got it done. So in the 70's her sisters offered to my Mom to finish the quilt (including hand quilting). the result? I have a beautiful quilt with a woven (not knit) lavender sashed embroidery quilt--with poly bat! doesn't matter--my g-ma and great aunts made it!(and the sashings and borders will never fade!)
