The Sweater of Sleeves is a short shrug mainly to keep your arms from getting chilly.
It is worked in the round at the beginning and the end, with a flat section in the center. You will need either a longish set of circular needles and work the magic loop technique OR a set of DPNs for the round sections and most likely some straight needles for the flat section.
It can be worked in any kind of yarn if the stitch count is adjusted for casting on. It will need to be in multiples of 4 for the ribbed cuffs and increase to multiples of 6 for the basketweave section.
