The back is done and it ate up exactly one third of my yarn. That long thread you see hanging from the cast off edge at the top is what remains of the 7th skein. This is making me very, very nervous. I believe there is a rule of thumb that the front and back should each take about one third of the yarn and the sleeves together the remaining third. So I should be right on track right? Apart from the part where together the fronts of this cardi are slightly wider than back. Oh and then there is that honking great collar which I expect will need about one and half skeins on it’s own. Hmm. I just called the yarn store and asked them to hold another 3 skeins. I don’t suppose I will be three skeins short, but I would rather not underestimate twice.
