Summit from Knitty, but a scarf rather than a shawl. I ran out of silk along the binding-off edge; I left it lying for a while, trying to screw up the courage to undo rows and rows of tiny slippery stitches so as to reclaim enough to finish off the binding properly. Couldn't do it. So I found embroidery cotton in a close-enough shade, and finished off with that.
It's ended up being a not-very-practical but still pretty scrap of silk, just long enough and just wide enough.
