What is the hardest type of repair to make?
Tears in a canvas are extremely difficult to repair. Once ripped, torn, or punctured, a canvas curls and distorts. Tears are mended using one of a variety of techniques, but it is not easy to predict how a particular canvas support will react to treatment. Once repaired, a tear is filled and textured to imitate the original canvas or paint texture. Tears often extend through numerous design elements and colors in a painting, so the process of inpainting can be quite challenging.
