A top-down, seamless version of the same design is available here. Knitted flat and and bottom-up in double rib and stockinette stitich. Looks great together with The Essential Beanie (free pattern available separately). A practical, unisex design that has been ideal play-wear for my children.

Note that there is a size 5-6 years available in the top-down pattern for this design.
