How does one properly make up a bed?

For many years some of the women in our family and I have had a running disagreement about the correct way to make up a bed. We have a very large family and share a summer cottage at the beach. We vacation together some in the summer and assist each other in up-fitting the cottage for our stay together. Sometimes while placing fresh linens on the bed during vacationing together, my mother-in-law and sister-in-law tell me that I am making up the bed wrong by placing the top sheet face down on top of the fitted sheet. They always make the bed up by placing the pretty side up and it is covered up by a light blanket. I always make sure the decorative trim side is at the top of the bed and then after placing a light blanket on top of the flat sheet, I turn the flat sheet down about 1/4, exposing the pretty side. Miss Manners, can you shed some light on the correct placement of the top sheet? This is not serious but an ongoing disagreement.
