I purchased a quilt 25 years ago in Amish country in Ontario Canada. The quilt, a Dresden Plate, has been washed many, many times and is still in wonderful condition today. I don't believe it is 100% cotton though - maybe cotton poly. However, many hours must have gone into the construction as it is entirely hand quilted with prairie point borders. I think with the beautiful cotton fabrics we can get today that with reasonable care well hand quilted quilts should last for decades. jmo.
