One of my sisters wants a black cowl and for her that will definitely happen, though it does remind me of one time when I wanted to knit someone a black scarf. I picked out a soft camelhair yarn to push myself to be willing to work with that color.
Small black stitches are of course harder to see to work with than when I was a 20-something and I confess I never finished that particular project–but the person never knew anyway, so, hey.
Turns out it was just as hard for a camel to through the needles with my eyes.
