Kate and I ventured off the beaten yarn-store track this morning, to la Bobineuse de Laine (translation: the Wool Winder) on Mont-Royal Avenue East. It's hard to describe this place -- there's a good blog post here about it. This is not brand-name yarn. The store is filled with cones of yarn that they sell by the pound. All of the prepared yarns are made up of several very thin strands, but they're not spun together; or, you can choose your own combination of various fibres, and they'll wind them together onto a cone on their huge old machinery.

I was looking at some boring dark blue, but Kate pushed me (nicely) toward the métallique mélange cones, and I ended up buying an 8-ounce cone of a white-&-silver mix:
