Darts remove a "V" shape from the fabric. The sides of the dart are called dart legs. They are marked on the fabric when it is cut, see page 7. To sew the dart, fold it in half placing one dart leg on top of the other, then pin the fabric. Look at both sides of the fabric to make sure the pin is going through both dart legs.
Fold the dart along the dart center line.
Pin the legs of the dart looking at both sides to make sure the pin is going through both legs.
Knot the end of the thread, then begin stitching from the point of the dart.
Sew a line of running stitches along the dart leg.
To create a knot, sew the last stitch twice, then loop the thread over the needle and tighten.
