Embroidery set pen / needle

The set contains a 10 cm long embroidery pen, 3 hollow needles and a needle threader.
Instructions: the embroidery cotton is threaded using a long threader. The needle is inserted into the fabric, it is not threaded, it should be perpendicular to the fabric. We pierce the fabric with a needle and pull it out just above the fabric and direct another injection a bit further in the direction of embroidery. Do not strain the yarn to prevent the stitches from mating.
