How do you keep darts from puckering?
Sometimes this can cause puckering if it’s not done absolutely perfect. At the end of the dart, simply leave a long tail thread and knot the end of it close to the point of the dart. To prevent a ‘shadow’ from appearing when you press, be sure to press the dart using a pressing cloth between the dart and garment.
How do you make a dart lay flat?
And marking the end of the dart 1cm back from the point also allows us to curve or “stitch into the dart” by extending the stitching line almost parallel to the edge of the fabric. This reduces the angle that the sewing line hits the folded edge of the dart and means the end of dart will lay flat and not dimple.
