This toddler cardigan is an adaptation of Kate Gilbert's "A Cardigan for Arwen" from the Winter 2006 Interweave Knits magazine (also available as an instant download from Kate's online shop).
I resized it for a 12-18 month old, altered the construction to make it a raglan cardigan and added toggle buttons and loops.
You will need to refer to Kate's charts for the very clever reversible cable.
US2/3.0mm needles for cardigan
