The pattern is a top-down construction with raglan sleeves.
all worked in the round changing colors and with cable rib.
if you like long sleeves instead of 3/4 sleves you can go on working the lenght you desire by continuing the decreasing of the pattern until the end; you will need one more ball.
the yarn is the soft and light Brushed Fleece from Rowan Yarns.
you can change it with another lightweight yarn.
4 balls grey, one light blue and 2 blue.
The size is a comfortable M/L, a little bit closer on the bottom for the cables.
