This sweater is knit seamless and from the bottom up.
The yoke is knit in two different colours.
Magic Loop is used throughout the pattern, but the sleeves can just as well be knit on double pointed needles, if preferred.
If you are not yet familiar with the principle of colour dominance when knitting with several colours you might want to do a little research first as colour dominance has a major impact on the look of the finished colour work.
