This pattern is available in Norwegian, and contains written text and chart. It will be available in English too.
The design is called Femgangen, which is Norwegian and refers to the 5 times table.
The sweater is knitted bottom up, and with raglan. Ribbing is used for edges. The fit is meant to be loose. If adjusting the length of the sleeves or body, remember it will affect the amount of yarn, and it will have to be done before the colourwork.
