Our lumbar size pillowcase is made from vividly printed 100% silk charmeuse. The pillowcase features a deep envelope closure to securely hold the insert. It is beautifully finished with French Seams on the inside. Gorgeous, detailed Coral print on a turquoise background. Perfect by itself, for layering with other sizes, and for Mix & Matching prints and materials. For scale, the images show the lumbar size layered before a standard bed size pillowcase in the same print. Fits a 21" x 12" insert. Our pillowcases can be hand washed in lukewarm water using a pH neutral soap. We recommend using Dr. Bronner's Castile soap or baby shampoo. Hang to dry. Iron on low.
