shape is pasted
Types of breakthroughs in size and shape are very different. Round shapes are rare, most often in the direction of the threads of the canvas. Breakthroughs are straight, angular, steps or zigzag.
Most often, breakouts are formed at thin canvases, thick ones are torn less often, but then it is more difficult to restore them. Before bursting a strong, dense canvas resists more strongly, at first it stretches to the limit and then breaks. Therefore, around the through gap, curvatures, bulges or concavities of the canvas are formed that affect the soil and the paint layer. Thin canvases usually tear more easily, with less deformation of the edges of the breakthrough and therefore it is easier to restore.
Due to the action of the canvas tension force, over time the edges of the breakthrough bend and do not converge. To restore such a breakthrough is Continue reading
