The leaf motif is similar to nightsongs, lyra … but smaller in size.
The backbone consists of purl,knit,purl and yarn over lines curve around some edges of the leaves.

A 150g skein of sea silk (654 yards) was enough to get a reasonable size: around 35” (90cm) from top to bottom at the midline and 63” (160cm) wide at the neck. But of course you can make the shawl as big as you wish by adding more repeats :).
