I did find some other options for an Entrelac scarf, however. I'm leaning to the reclaimed brown and blue stuff. It made a crappy sweater, but maybe there's hope for it as a scarf.
The rusty grey one is another option. Hmmm, fingering weight versus bulky. Since I consider scarves to be instant gratification type knitting, I'm thinking bulky.
The rusty grey one may become another 198 yds. of Heaven shawl - only made slightly bigger to use up the wool.
The merino-silk-linen blend FibraNatura is another option, but since I have about a sweater's worth of it - I'd rather make a sweater.
What really ticks me off is that I was sure I had another ball of the Milli Colori! I rarely buy individual balls of anything, so having just the one of this makes no sense. And I know I bought it a while ago, so matching the dyelot is a pipe dream...
