I have original Aunt Graces fabrics that were made by Benatex and they are not lightweight at all, rather a little over starched in production. I wouldn't ever use anything lightweight in a quilt because the thread will tear thru the fabric when washing very quickly. I have always used Hobbs 80/20. Harriet Hargrave taught me many decades ago, to buy the best fabric that you can afford. Good Luck !!
