Consider buying a bedspread large enough to go all the way to the floor. Then place any quilt that no longer covers the mattress sides over the bedspread. It is a nice way to enjoy a treasured quilt. In my case, thanks to the mattress which is deeper than the previous mattress along with a 4-inch memory foam topper, I found a king size bedspread perfect for our queen bed. Bedspreads are somewhat difficult to find in stores, and they are more available online. Thin bedspreads are not easy to find, either.
