We have a rectangular sweater, ladies and gentlemen; all the better to argyle with. The only shaping is at the front neck. The sleeves have one diamond motif down the middle-- the rest on either side is plain.
The red diagonal lines are added afterward in duplicate stitch. So this whole argyle experience is really just a matter of intarsia diamonds, and anyone can do that, right? And then you have a perfect slouchy, comfy dorm or casual sweater for the rest of your life.
