Ideal for experimenting or creating final artwork with acrylic and oil paints, Strathmore 300 Series Cotton Canvas Panel Packs are made from 100% cotton and triple primed for an economical, acid free surface that lets you get right to work. Panels feature a medium grain texture that renders detailed brushwork beautifully, yet they’re sturdy enough for heavier applications including mixed media, collage, and impasto. Panels have a primed weight of 12 oz.
