Writer Painting support
A material that supports the ground and the painting or drawing. This is the surface you paint on. Common painting supports are canvas, linen, tempered high-density fiberboard, medium-density fiberboard, birch plywood panels, or, if you want a really light painting support, use linen or canvas mounted on gatorboard. I use medium-density fiberboard or mahogany plywood (brand: luan) for small painting supports, 9x12in (23x30cm) and under, and either high-density fiberboard, birch plywood, or stretched linen for larger painting supports.
