I received two double knit quilts as a gift way back when double knit was the "to have fabric". Both have a muslin type frabic as the backing, were quilted using batting and were quilted not tied. They have had a rough life as they were my son's favorite quilts. They have survived being tents, dragged to ball games,car races and a lot of road trips. However, they have shown very little wear and tear. If possible, I would use batting and quilt it.
