The vest is knitted in three pieces, one for the front and two similar ones for the back. This pattern is knitted top to bottom. The final rib will only be knitted after the three pieces are stitched together, though it can be knitted separately; it looks better if knitted at the end.

This rainbow jumper uses white as main colour for the body and the sleaves, and the 7 colours of the rainbow for the yoke.
