For this sweater I used different shades of Blue!

The colorwork is also nice when you stay in one colour familiy, here I combined 2 different shades of blue with a light grey:

Here is the yarn requirements per color for size 34 3/4’’ /88.5cm:
4 skeins of “Colonial Blue” Heather,
1 skein of “Cobalt Blue” Heather
1 skein of “Light Gray”

And for the cool cats: the pocket lining and one thumbhole in contrast colour!
