Understitching by hand

I've got the facings lining of the LWD clipped, pressed, and turned, and now I'm hand-understitching it, using a small backstitch. I get the distinct impression that this gives a softer, more flexible edge than machine understitching. You can also get all the way around sharp curves and corners, no problem.

Also in this case, I don't like how the thread I'd have had to use in my machine looks against my lining fabric — just as well it isn't visible in the lining seams. (With the very thin needle I've had to use for my dense silk crepe lining, my machine refuses to push the better-matching but slightly-too-heavy silk thread that I have through the very dense silk crepe; I've had to use thin cotton "darning and embroidery" thread instead.)
