These 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 with most media. Artist Series panels are double-primed with an acid-free acrylic titanium gesso. The sides are completely turned under and glued to prevent fraying and separation. A versatile option for oils, acrylics, water soluble oils, paint markers, permanent markers, spray paints and alkyds. The 6-Packs and 12-Packs include panels shrink wrapped as a pack. The 3-Packs include individually-wrapped and UPC-labeled panels shrink wrapped as a pack.
