You make a dart by drawing a triangle with a fabric pencil. Fold triangle and match ends. Pin at bottom point. Pin at the top making sure the ends match. Sew starting at the bottom and backstitching.
If you have a t-shirt that is too big, try sewing darts in the t-shirt, on the back and front for a better fit or just for a different look. Watch the video below then find an old t-shirt and practice making darts.
