Super Chunky, Super Funky, right? This set is absolutely lush. That texture just has a hold over me, the subtle check pattern of knits and purls leading into that sumptuously smooth stocking stitch and then... oh gosh, completely textured sleeves... I'm in love. I really think you should wear the jumper AND the hat AND the scarf all at the same time for maximum smooshiness.
You'll need 8mm and 10mm needles, and a stitch holder for the jumper.
