Dart (sewing) pattern without affecting fit, the length of the dart intake at the edge of the fabric is not a good measure of dart intake. Rather, the angle subtracted from the pattern by the dart is what determines the dart's intake. As long as the focal point of a dart and its intake remain the same, a dart can be rotated around its focal point, or stylized in one of several ways without affecting the fit of the garment. An easy way to rotate a dart on a flat pattern is to slice a straight line from the dart point to
