Double Back Stitch (for Pulled Thread)
The Double Back Stitch is the shadow work stitch but pulled with a slight or medium tension. This stitch is worked over two rows and can go in any direction. This is one stitch where a slightly different colored thread might be appropriate. The crossed patterns on the underneath of the fabric comes through the fabric, thus the name “Shadow work”. It also seems to give a little more dimension to the fabric caught in between the two rows.
