Finished dimensions:
8.5” x 23” in the round

This is a Colour work cowl knit in the round and fits snugly around the neck and chin without it being too tight.

This was knit on 22” circular needles using DK sw merino tweed. The contrasting colour contained a fair amount of the main colour and once knitted produced a subtle mirage effect.

The yarn I used is from Vivid Yarn Studio: Vivid Yarn Studio Donegal Tweed DK, which does not appear on their website any more. Any DK weight should work.
For Colour A, I used about 1/2 of a 100g skein (~110 yards)
For Colour B, I used about 1/4 of a 100g skein (~60 yards)
