I always use sheets would do it no other way and have had no problem with them at all. I also go to Thrift stores and buy them
and store them in Big Plastic Bins, I'm one for saving every penny I can , I figure the pioneer's had it right and there's are still around today and doing great, so if it worked for them why rock the boat now, when this is why we are carrying on the fine art of Quilting to pass it on as they did for use. :D
