Hair strands or hair tufts (7) are stitched in loop form on a flat, flexible base (2), for example a textile base, in a region bounded by a desired hairpiece contour (1). The stitched region is then removed from the base (2), by being cut out or stamped out, along the periphery (4) of a border (3) which encloses the hairpiece contour (1). Finally, the resulting flexible hairpiece is slipped over onto part of a toy figure, and possibly adhesively bonded thereon, and the hair strands or hair tufts are cut to length and combed. The method makes it possible, in a simple and cost-effective manner, to provide toy figures of any size, even those made of a hard material, with hairpieces of any appearance.
