Note, saw a video Nancy Zieman where she explained that any fabric works for quilts but in a denim one must use 1/2 inch seam rather than 1/4 because it will fray. of course if it's serge finish then don't see the need. My heirloom quilts have curdoroy next to cotton next to silk all work well, but some wear out more than others, in between relatives used up their old sheets rather than batting.
