I’m really dense here but I don’t u derstand why someone wild go to all the trouble to make a nice quilt top and then use an old blanket as batting. I started my quilting journey in 1979 when batting was - in a word -crappy. But we did have a few nice flat brands that were 100% cotton or almost. Thrifty ismine thing but I just don’t get - why. Unless you had a nice wool blanket.
