There are three different qualities of canvas frame to match the paint. KREUL Canvas Board and KREUL Stretched Canvas are ideal for beginners. The canvas frames in the SOLO GOYA Stretched Canvas Basic Line are available in medium quality. Artists choose canvas frames from the SOLO GOYA Stretched Canvas Premium Line for more exacting requirements. The bars of the frame are manufactured from FSC-certified pine. Depending on their size, the frames are stabilized by means of a middle bar or cross. The canvas itself is folded back and stapled to the rear side.
