Manneken is a pullover with a special construction.
There is no sewing, seaming or intarsia involved. First the top of the sleeves is worked bottom up starting with a provisional cast on. Then, the body is worked top down, seamlessly joining to the sleeve tops as you go.
The provisional cast on is unraveled and the sleeves are worked top down.
A mosaic stitch pattern finishes the bottom (only one color is worked per round).

A special, clever bind off method is used to obtain minimal finishing and to prevent stockinette stitch from rolling. Photo tutorial is included.
