It was bought at Loehmanns. However, I saw the same scarf in different colors today and that one was from Macy's.

The scarf-wearer is a knitter also and we talked about how to knit it. To me, it looked a lot like the Sarah Blanch Shawl (Ravelry link) from Folk Shawls. The stitch pattern is garter drop stitch.
Believe me, I have enough knitting on the needles right now! But maybe sometime in the future IF I need something easy-peasy and IF I have some oddball yarns around and IF I remember this post, this would make a good project.
