A revolutionary watercolor surface made of 100% cotton! The unique texture of an all natural woven material, in combination with a proprietary patented specially formulated acid-free coating, delivers a unique watercolor painting experience and distinctive look that can only be captured on canvas. Available in a roll form for creating a stretched canvas using stretcher strips. Has a great “lifting” ability, watercolor washes can be “lifted” easier than on watercolor paper. Will not tear like watercolor paper can, so you can scratch it, scrape it, staple it, wet it, and re-wet it. You can even washout the entire image and start over! Will not buckle when wet. Great for large paintings! 7.7-oz.
