I used one skein of Knit Picks Chroma in Hollyhock with size 6 circular needles. This scarf is not worked in the round, but I used circulars just because I tend to prefer them.

BO using JSSBO. Fasten off. I left an extra long tail so that I could seam the ends together after blocking, but you could also just add some more yarn. I blocked this lightly to stretch out the stitch and make it more even. Blocking also helped reduce the curling of the edges very much. I was sort of worried about how much the edges curled, but after blocking it, just wetting and pinning it down, the edges flattened right out.
After blocking, seam together and weave in all ends.
I loved watching each color emerge as I knit on, with the vibrant purples, indigos, and greys. As I said, I've never used this yarn before, but I really enjoyed it and will definitely be using it again.
My finished cowl is 29"x11" after blocking.
