Ready for winter!

Finished knitting a chunky wool jumper today    -  glad I am good at maths - I wanted to make the sleeves one and a half inches longer than the pattern said, but didn't know if I would have enough yarn so I did a total stitch calculation (28724), divided it by stitches per 100g yarn(4830), and decided the 6 balls I had would just be enough - it would do 28980 stitches! The extra pic shows the small amount left over - it would not have been enough for another couple of rounds of the neckband so I was spot on!
