Millford Watercolor Paper is made with 100% cotton and a unique hard sizing that keeps paint on the surface longer. #ad The fibers are placed more randomly, helping the sheet stay flatter with less buckling while you work. Colors stay bright, washes stay controlled, and it lifts beautifully, even with staining pigments. It also handles masking fluid without damaging the surface.
