I made my way to the yarn shop yesterday, after a brief conversation with my resident physicist, who tells me that green should be at 0ºC. Who ever heard of that? Oh, well, it kind of makes things easier to just have a spectrum of colours.
Red for hot, through green at 0, to blue and indigo for cold. I'm hoping I don't have to get more colder yarns, because it's already freezing during the day, and, in fact, snowing at this very moment! (I will resist the obvious temptation to use some sort of fuzzy or sparkly yarn for snow days.)
The darkest blue, on the right, will be for -15º and lower, bright blue for -10 to -14, pretty variegated icy colours for -3 to -9, and green for -3 to +3.
Green variegated for 4 to 10, yellow variegated for 11 to 15, yellow/orange for 16 to 20, orange variegated for 21 to 27 and red for 28 and above.
I was worried that I'd need more on either end of this scale. That is why the colours have to stretch to a bit more (sometimes) than the 5 degrees I had initially thought. Also, it's the time of year when all Torontonians forget that it ever gets warm here. We are bundled up for our months and months of cold and can't think beyond that. Really, it'll be 28 degrees here sometime in the next year??
I'm sure that if next October I find I need more 10º yarn, I won't be able to match dye lots or even colours, but then again I am equally sure that I can't need more than 160 metres of any one colour. Right?
This all gets lovingly put away till the winter solstice, when I shall cast on. Cast on what, though? A plain garter or seed-stitch scarf? A 10-stitch blanket? I think I'll find a two-row lace pattern and make a scarf out of that.
But who knows, it's weeks away and I have a man-sized sweater to finish!
