Scoop up the needles you'll need for the Plaid Party Cardi right here. The needle sizes you'll need for the sweater, shown here, are US 15 (10 mm) 32" and US size 17 (12.75mm), 40" long. 

Chiaogoo needles are our top pick because of their fantastic quality. The thick plastic cable is stronger and wider than you'll see on most large size circular needles, making it easier to knit chunky yarns on.
