20" x 20" Thick Canvas Raw Materials

Raw Materials Fundamentals Stretched Canvas is assembled right here in Southern California using bars made from sustainably-harvested Douglas Fir from Western US sources and 7oz 100% cotton canvas from India, double-primed with acid-free acrylic gesso (so ready for use with oils or acrylics), wrapped with seamless corners and staple-free edges.

The canvases come with four different types of stretcher bars: the Slim bars are ¾" deep, the Thick are 1½" deep (but lightweight, like the Slim bars on their edge), the Chunky are 1½" deep (and broad), and the Epic are 2½" deep.

In addition to all of the stretched canvas we have in stock, you can order custom-stretched canvas in any of the four varieties. Contact us for quotes on custom canvases.
