Here's the finished Sisika Scarf:
I'm actually really pleased with it, though I can't say I'll be running out to find crazy-ass variegated yarn again any time soon.
In the end, my version was shorter than the pattern suggested it would be and, because I was working with a double strand of yarn - from 2 balls simultaneously - I was extra-concerned not to run out of yarn. I probably could have got one more six-row repeat out before the closing sequence, but I wasn't gonna chance it.
What do you think?
