Chiaogoo needles are our top pick here at Knit Collage because they have a smooth join and are great for beginner and advanced knitters alike. The needle sizes shown here, are US 9 (5.5 mm) with a 32"/ 80 cm and a 40" / 100 cm fixed circular cord. These needles will work well for our Serenity and Spun Cloud Light patterns.
