Grillage by Aurelie Colas is meant for multi-coloured yarns. I'd been given this self-striping black and red yarn by a friend and knew it would be great for this pattern. As it turned out, coincidentally the length of the stripes is almost exactly the length of the pattern repeat too! The red and black does remind me of Dennis the Menace, though.
I'd definitely make these socks again for other similarly loud yarn!
