My Mom and I went thru her thread boxes last fall and she gave me loads of Coats and Clark spools that are probably around 20-30 years old. I use them when I turn and hand-stitch the binding. She had quite a variety of colors (some pretty funky), so now I have thread to match pretty much any fabric. I use Aurifil in my machine, but like the Coats and Clark for stitching the binding.
