Step 1: Understanding the Concept:
Shadow work is a technique in which stitches are worked on the back of a sheer fabric. The coloured threads show through the cloth as a soft, faded shadow on the front.
Step 2: Key Facts:
Shadow work is a famous feature of Chikankari, the white-on-white embroidery of Lucknow in Uttar Pradesh.
It is done on fine, light fabrics like muslin, voile, organdy and georgette.
The stitch is called herringbone stitch (also called closed herringbone). It is worked from the wrong side.
The result is a delicate shadow effect that is seen on the right side.

Kantha uses running stitch on layers of old cloth.
Phulkari uses darning stitch in silk floss on khaddar.
Kashida of Kashmir uses chain stitch and satin stitch for its motifs.
