Herringbone stitch

Sewing by hand is a meditative activity- though "meditative activity" is rather an oxymoron. 
I've become quite comfortable sewing by hand, and have recently learned new techniques.
The herringbone stitch is versatile; here it is concealed, on the inside of a shade, but it is also an attractive decorative finishing stitch.

Domette is a thick, plush, rich cotton interlining that adds a sumptiousness to layered fabrics that regular interlining cannot match.
If widths were sewn right sides together, the pressed-open seam would create a bump that must be avoided because the face fabric is a fine dupioni silk. 

Hence, today's meditation: joining overlapped widths of Domette Interlining by hand with a herringbone stitch.  

The visible herringbone will be the wrong side; on the other side it appears as two rows of running stitches.  The two rows make this join exceptionally stable.
After the fabric is lightly ironed and steamed to set the fibers and the thread, the selvedge melds into the other layer creating a very smooth join with no lump or ridge from a seam allowance.  This overlapped join is precisely aligned with the seam that joins the widths of silk.
