This pattern that now also provides a buttoned cowl version.

Now Pure Silk Yarn in two colors available in my Etsy store CraftStruck -- https://www.etsy.com/listing/85940264/lace-weight-3-ply-p…
to knit this scarf or cowl pattern.

As a lover of nature, it is fascinating to observe how trees continue living even as leaves fall. The design of the scarf tries to capture this cycle of life of creation and destruction. While one tail of the scarf depicts the falling of leaves, the other shows them blossoming and thriving.
Knitting it with 2 ply makes it delicate and drapey.
Repeats of 48 rows which makes 3 leaves at either end makes up the scarf or cowl.
