my mother uses polyester double knits to make all her quilts that she gives to her grandchildren, greats, & great greats. She is over 80 and still going strong. Over course polyester doubleknit never wear out as they used to say, last forever. Our ladies aid made these types of quilts for the missions also. Just used knits for fronts in bigger pieces like 10 " and used flannel sheets or regular sheets on the back, they don't need batting as they use them to divvy up into rooms or throw them on the ground and sleep on them. Hope this helps you out. What a wonderful gift she gave you.
