Our cotton canvas pillow covers are made from 100% cotton fibers. This fabric has a thick, tight weave that is effective in preventing fraying and thread unravelling. This material comes in natural beige color. The fabric density of 10 oz/ square yard allows for full pigment absorption, which makes it great for painting on. This fabric is cost effective and therefore great for school art and sewing classes to practice painting, shaping, and sewing. These pillow cases come with a color matched hidden zipper for easy removal of the inserts. These are covers only, pillow inserts sold separately.
