Winsor & Newton Professional Watercolor Block, 12" x 16", White, 20/Sheets (WNX6664004)

Create expressive, large-format watercolor artwork with the Winsor & Newton Professional Watercolor Block, Cold Press, 12x16 in, 300 gsm (140 lb.). Crafted from 100% cotton for exceptional strength, absorbency, and long-term durability, this artist-grade block is designed for watercolorists who rely on consistent performance and surface stability. The cold-pressed texture offers a perfect balance of subtle tooth and smoothness, enabling everything from soft, even washes to crisp details, glazing, and layered techniques. Each sheet is glued on all four sides, keeping the paper perfectly flat while you paint, even under heavy water application or repeated layering. This eliminates the need for stretching and ensures minimal buckling. Once your painting is fully dry, simply release the top sheet with a palette knife to begin again. The generous 12x16 in format gives artists a spacious surface ideal for landscapes, portraits, expressive studies, and finished exhibition pieces. Winsor & Newton's Professional Watercolor Blocks are archival, acid-free, and engineered to preserve color vibrancy and structural integrity for generations.
