This canvas panel is made of 100% cotton canvas with medium grain texture. The cotton canvas holds paints well and keeps the paints with their natural tones and glossiness. The acrylic triple gesso primed acid free canvas creates a non-yellowing surface and makes the painting surface ready to paint, collage, draw, sketch and illustrate. These canvas panels work great with acrylic and oil paints. The rigid board is made with paperboard, which is smooth and firm. There are 3 boards per pack North Shore’s canvas panels are a great value
