for aesthetic, rather than practical reasons, most of the glued-on pieces of fabric are also embroidered with small stitches or small crosses, using 1 or 2 strands of yellow, red or gray embroidery thread.
The unembroidered pieces are given a 3D effect: the red wings, the white head, the piece of cloth and the eggs.
The large hen's legs are embroidered using the
tambour or chain stitch (which creates a better raised effect), the eyes are made of black French knots.
