Daler-Rowney Premium stretched canvases are now made in the EU to the highest specifications. They are made with a superior-quality heavyweight (380gsm), acid-free, 100% cotton, medium grain canvas and professional stretcher bars in heavy wood for improved strength and optimal stability. The canvases have been given three coats of acrylic primer; triple-priming creates a perfect ready-to-use painting surface for both oils and acrylics that holds the colour on the surface and prevents seepage through to the back. The canvases are stapled on the back to give clean edges and come complete with wooden wedges to adjust tension in the traditional manner and they are individually wrapped to protect the surface.
