Darts are crucial in pattern design as they turn a flat, two-dimensional piece of fabric, into a three-dimensional shape.
A dart is created by two lines that form a wedge, and meet each other in the dart point. When the lines are sewn together they create a permanent fold, preventing the fabric from laying flat, thereby creating a three-dimensional shape.
> Entire chapters in books on sewing and pattern design are dedicated to darts. Knowing how and where to use them is not so simple. But for this website, knowing what they are is sufficient.
