I inherited a quilt top that is about 70 years old from my mil that was hand sewn by her grandmother. It was never quilted. I intend to hand quilt it but I need suggestions on what kind of batting to use, and what fabric to use on the back. It has to be all cotton because of its age but don't know if it has ever been washed. Should I hand wash it first? Should I add a border? Any help would be greatly appreciated.
