Stretched canvas. This professional-grade canvas from the Premium Line is made of 100% natural cotton with a weight of 380 g/m², offering a durable and responsive surface suitable for all types of paint, especially acrylic and oil. The canvas is stretched over a blind frame made of high-quality spruce wood, kiln-dried to 12% moisture for optimal strength and shape stability. The wooden strips measure 3.5 × 2 cm, providing a robust yet lightweight structure. Reinforced stapling keeps the canvas firmly attached to the frame, making it ideal for heavier painting techniques. It is tightly wrapped over the edges and secured underneath, allowing you to paint on the sides without the need for additional framing. Each package includes 8 beechwood wedges for easy tension adjustment, ensuring long-term stability and a professional finish.
