These 3mm ‘ready-to-paint’ linen look canvas boards are made from 75 percent cotton and 25 percent polyester. Features universal transparent coating, they are perfectly suited for oil and acrylic painting. This classic material is ideal for artists as it is more rigid than paper, but less cumbersome than a frame. Acid-free, the colours are preserved. The canvas board is 3 mm thick and available in a variety of sizes.
