Canvas Panels are great for students. The surface texture provides a
very definite paint-gripping "tooth" with minimum paint absorption, a
perfect support for painting in all media. The sides are completely
turned under and glued to prevent fraying and separation. The entire
area of canvas is firmly glued to the board. The sizing is acid free. We have tried a lot of different canvas boards over the years, but this is the only one we have tried that really resists warping.
