Finished Object: this snuggly cowl:
yay! this is how it started life, as undyed aran yarn from Wooltops:
and I used a long-gradient dye process so it goes from burgundy at one end, gradually down to the white yarn at the other end, with shading of lighter purple, red and even blue inbetween.
the pattern is something I improvised, guessing that a diagonal slant would show off the gradient changes well, and I’m really happy with it!
