Winsor & Newton Professional Watercolor Block, 9" x 12", White, 20/Sheets (WNX6664002)

Paint with confidence and premium stability using the Winsor & Newton Professional Watercolor Block, Cold Press, 9x12 in, 300 gsm (140 lb.), an artist-grade surface crafted from 100% cotton for superior strength, absorbency, and long-lasting durability. Ideal for both studio work and plein air painting, this block features a cold-pressed surface with a balanced texture that supports expressive washes while still enabling fine detail, controlled glazing, and subtle gradients. Each page is glued on all four sides, keeping the sheet perfectly flat as you paint, even with heavy wet-on-wet applications. This eliminates the need for stretching and prevents buckling, making it easy to build layers, lift pigment, and create smooth transitions. When your painting is complete and fully dry, simply slide a palette knife into the unglued corner to release the sheet and reveal a fresh page underneath. The 9x12 in size provides ample working room for landscapes, portraits, studies, and finished pieces while remaining portable for travel. Winsor & Newton's Professional Watercolor Blocks are archival, acid-free, and exceptionally stable, making them a trusted choice for artists who need dependable, professional performance.
