Our range of Winsor & Newton linen canvases provide an exceptionally strong, smooth surface for oil and acrylic painting.The 390gsm, acid-free and archival-quality linen provides superior longevity and is tightly woven for a more even texture than cotton cloth. The stretcher bars are made of spruce wood, which is kiln-dried to finish, increasing its resistance to warping and making it even better at protecting against moisture. The canvases have a depth of 0.75 inches, so they are robust and sturdy without being bulky. Every canvas is primed with richly pigmented titanium dioxide Gesso, giving them the perfect level of both tooth and absorbency. They are all hand-stretched, but also come with wood keys should you wish to control the level of tension yourself. - Size (Inches): 16inch x 20inch - Size (cm): 31cm x 51cm - Material: Linen - Fabric weight: 390gsm - Depth: 0.75 inches - Quantity: 6 canvases per pack - Backing material: Spruce wood - Stretched: Yes, by hand - Primed: Yes, with highly pigmented Gesso - Texture: Very smooth - For use with: Oil and acrylic paint - Additional features: Wood keys included
