That looks very pretty! I love the colours and the ribbon-like yarn.
My grandma used to knit scarves in that pattern for church sales, always in grey as she and many ladies her age wore the (local) Scheveningen costume - not to be confused with the so-called Dutch costume, which does not really exist. She called it the Lazy Women's stitch.
I love how it looks in your sweater and thanks for the memories.
Glad to bring back memories for you.......this stitch gave a great drape along with the ribbon yarn....also it was fast!
