100% Dupioni Silk Valances, Set of 2. NWOT. Silk Dupioni fabric's distinctive feature is the excellent glimmering effect it produces when moved around in light. This is due to the fact that it generally has two colors in the weave. This listing includes two valances made in beautiful soft yellow color (my photos don't do justice to their beauty). Each valance covers a standard windows that measure 31" to 36" (as shown in photos). Approximate Meaurements: 50" x 16.25"
