Red Label Artist Series is a professional-quality stretched canvas made from 100% cotton duck with a medium texture. The 100% cotton 7 oz canvas is triple-coated with bright white acid-free acrylic primer over a buffered acid-free sizing layer that protects the fibers from direct contact with the priming and resists acidic deterioration over time. - Fredrix Red Label Cotton Canvas - 12 x 24 3/4 ProfileFrdrx Red Label 3/4 12X24 -.
