If I'm not mistaken, what we have here is a pile of knitted sweater pieces.
As I predicted, the birthday came and went without a finished sweater. I did manage to finish the knitting, and I wove in all the ends. The end-weaving was no small feat; these balls of yarn had a concentration of knots that would have made Debbie Bliss proud. I do love weaving in the ends before I block. It makes starting the seaming so much easier if I don't have to think about that additional step.
