Monterey Premium Cotton Canvas, 7 oz. raw and 10.5 oz. after priming, has a medium weight and tooth surface and is suitable for use with acrylic, oil or alkyd paints. Stretched using MasterWrap technology, this canvas offers a drum-tight, archival surface that can be further adjusted using the pre-installed corner and brace keys. Folded corners and extra canvas selvage allow for re-stretching, and the clean staple free edges are great for display without a frame. The solid, finger-joint free, kiln-dried bars are milled with lumber harvested from sustainable forests in both Oregon and California. Key-able cross bracing offers additional strength, stability and warp resistance.
