This quality canvas by Fredrix is composed from medium textured, duck canvas of the highest quality. Its double-primed build also features acrylic gesso. This acid-free material is ideal for acrylic or oil painting, giving the artist a wider range of options. The standard stretcher bars are attached to the actual canvas by staples so it's possible to paint on every edge. This canvas can actually dry with or without so much as a frame. Fredrix is one of the most trusted names in the art world, and this specific high-quality canvas is just one example of the superior products they create.
