From Knitting New Scarves:
Here’s an eye-catching scarf that usually elicits a range of interpretations, from a comparison to octopus tentacles to a seemingly unrelated craving for little powdered-sugar donuts. Neither tentacles nor donuts were my inspiration, which actually came from the round windows of an exotic freeform house in California. If you love knitting around, you’ll be in knitting heaven. Circles requires knitting around for the tubular body of the scarf, and then knitting around again and again for each of the decorative circles.
Requires four US 10, four US 10 1/2, and two US 9 double-pointed needles. Also requires a stitch marker, tapestry needle, and 15 yards of lighter weight contrasting scrap yarn to be used and discarded in the process of knitting.
