I have a DWR quilt with some scraps of Liberty of London lawn fabric. It was made 35 years ago and was used on my bed for 25 years, with frequent machine washing and drying. The liberty prints were the first to shred. The colors never faded. As a side note, the solids in this quilt were poly/cotton, which was all I could find at the time. They still look great.
My niece ordered crib bedding from Restoration Hardware recently that is made from voile, which is similar to lawn. It looks so airy and soft. I would love to have a summer quilt from voile or lawn-- I would take better care of it than my DWR.
