I’ve finished the first end of the EG. The pattern says to start with a waste yarn cast on, knit the middle section and one tail, then pick up the open cast on stitches and knit the last tail. As I have barely enough yarn and I want to make the scarf as long as possible, I wanted to know exactly how much yarn a tail needs (10.1 g, it turns out) so I can continue with centre until I have just enough left for the second tail. I took a picture of the first tail before picking up the cast on. It’s pinned out but not stretched for proper blocking.
