Despite this, I am quite pleased with progress with J's jumper.
Last night I finished knitting the right side of the neck. Tonight I have done the neck border and one armhole border. These have been quite quick to knit as there are only four rows of rib before cast of. This means that tomorrow I should be able to knit the border on the other armhole and just have the side seams to sew up.
I may even get to finish this with a few days to spare until the end of the month.
