This canvas is a high-quality, economically priced canvas with a staple-free 3/4" deep profile and key-able corners which allow for tension adjustments. Stretched using a double acrylic, primed Belgian linen and Masterpiece's MasterWrap technology, it features a drum-tight, archival surface for oil or acrylic paints. Linen is the strongest natural fiber and provides a unique surface texture. Solid, finger-joint free, kiln-dried bars are milled with lumber harvested from sustainable forests in Oregon and California.
