The pattern is Aran Sweater by Kate Gunn and Robyn MacDonald. I made the size 6-7, but unfortunately did not pay much attention to the finished measurements - the chest is over 80cm, with the other measurements in scale to this large size, so it fits my 11 year old daughter beautifully.
I used Sirdar Denim Chunky and my tension swatch was just fine. I do think the cotton content has made this jumper a little more stretchy than it would have been in the wool for which the pattern was designed. However, the wool/cotton blend is a much better weight for our climate.
