This was inspired but the glass floats used on fishing nets that have washed up on the Oregon Coast. (Now they are produced as art pieces at the many glass blowers in the region.)

Only one color is used per row.

Slipped stitches are always slipped purlwise with yarn held to the wrong side.

The Aqua and Tangerine version ends on row 154. I have extended the pattern so one can make a larger shawl.
