First Graph of the Spiral Cowl

I have created a first graph of the Spiral Cowl. I am hoping to make gentle spirals to mimic the spiral jetty underwater when we saw it. Just the hint of a spiral under waves of blue.  At first I was thinking of dark grey yarn like the basalt the Jetty is made from but now I want blue for the underwater jetty. Although the lake can be many colors depending on the day – blue, pink, green, grey, brown – the day when I first made the trek out there, the water was blue.
