The Stickstich, which we named now shadow stitch we can find it under the cross stitch in the old needleworking books. Sometimes joined garments or items of washing with a cross stitch as you hem by the hand. Two pieces of material, which laid on each other, were knitted above from the left side with a closed witch stitch. At the upside results two parallel continued quitting seams. If the used material was transparent, the witch stitch shimmer trough. Was it may be the hour of birth of the present shadow stitch?
On a fine linen or cotton batiste we can find the shadow stitch in old linen embroidery. In it there were performed tender leafs, cirrus and blooms. Today we marvel on the lace embroidery about the diminutive shadow twinges, which made for the boundary of the pulled thread work.

The picture shows a special nice Dresdner lace (Point de Saxe) from 1764. This lace is preserved as it’s founded from a loom 230 years ago. The knitter hasn’t cut the edge out to the head. There are some embroidery samples visible yet.
