Yikes! Math problems!
I've been using the shawl percentage calculator. Um, ok. I've done three full repeats of rows 19-42, plus 9 more rows. So I've worked 123 rows of the shawl. The calculator tells me that I've done 26.9% of the shawl. Depressing, but whatever.
So I went to my handy dandy scale and weighed my yarn. I've used 34g of the 50g ball of Misti Alpaca laceweight. That's 34% of my yarn, and I've only done 26.9% of my shawl. That's a big fat, ugly problem. Especially considering that I ordered it online and the chances of getting the same dyelot are probably like nil.
Even if I take out a full repeat of the five, I'm still cutting it way too close. I'll have used 34% of my yarn and only done 33% of my shawl. What if I find a knot? What if I have some other sort of colossal screw up? I am one unhappy camper!
ETA: Shoot I miscounted the rows. I'm even worse off than I thought.
