As I work on my Ulmus, one of my biggest concerns is if I have enough yarn. Luckily, someone has done the calculations to help me (and you) figure out if I have enough yarn (if you are knitting a rectangular or triangular shawl). With it, I’ve determined that I’ve knit about 35 percent of the shawl but have used only 25 percent of my yarn. I have enough yarn… I think. (I hate math – I will re-evaluate as I knit more rows.)

So check out this blog post from ‘I’m knitting as fast as I can‘. Maybe it will help you too.
