Shaped heads can also be made with a row of running stitches around the top, which are drawn together once the head is stuffed: The BALL HEAD is simply created using a circle of fabric around which a row of gathering stitches are sewn and inside which a clump of stuffing is enclosed, when the threads are drawn up. Two rows of stitches creates a stronger seam. The stitches are then tied off, knotted securely and neatly trimmed. The ends can then be hidden at the back of the head behind the hair.
This type of head produces a three dimensional shape, achieved by inserting darts / sewing across the seam at chin/neck/eye level to produce better shape and dimension.
This is a clever way of manipulating the bias of the fabric in a 2D profile head, by sewing two rectangles of fabric together, refolding them right angles to the seam, applying the head template across the seam and sewing this before cutting, trimming and clipping.
