Clarification - for row 1 of 2nd and subsequent repeats:
Kfb, knit to the marker, sm, I8, k1.
Designed to make a scarf-sized accessory (approx. 150cm/ 60” long) with just one skein of DK or worsted yarn. You will need scales to weigh your yarn.
Eliminating the bulk at the neck edge that you can get with a standard sideways construction makes for a more elegant line and also makes the yarn go further.
There’s quite a bit of text to guide you through the process, but this is very simple and intuitive to knit.
You can also use more yarn to make a larger scarf, shawl if you like.
Many thanks to the testers:
