I find the larger needle sizes easier to work with when knitting this type of yarn. Shorter needles are also less apt to get snagged in the yarn than longer needles, but a short (16”) bamboo circular is my preferred option. (No slipping, no snagging.)

I made the 8 stitch wide version of this scarf. There is a tendency for the cast-on edge to flair out significantly more than the cast-off edge with this type of yarn, so I compensate for that by casting on only 4 stitches to start, working those 4 stitches for 2 or 3 rows, and then increasing to 8 stitches for the remainder of the scarf. I also used my home made rig for working with this yarn (which you can see here).
