Often making the correct pattern depends on how we attach it to the cardboard. It's so simple, but at the same time a critical point in the process of work on the basic pattern. But with the help of two simple cuts on patterns we can easily fix it. If we glued pattern below the desired angle, then we close it in the incision. If it turned out with a sharp angle, we will open it in the incision. To do this, you first need to find the lowest point in the pattern curve at the front of the last. It is located in the center of the intersection of a straight line drawn from the middle toe and the other a straight line drawn from the center of arc.
From this point it is necessary to draw a straight line down and incise it to the middle. Then back down 2 mm and then continue to the end of a cut in a straight line down. Thus, closing the incision at the top (or, opening, depending on the need), pattern angle is reduced, and opens at the bottom at the same time. The pattern is not deformed, and is easily corrected by using these two simple cuts. And you don't have to make a new pattern with a scotch tape.
