I managed to find 6 balls of Rowan Damask yarn in a charity shop for £1.50 (for all 6! - I didn't realise at the time what a bargain this was). Four weeks later I have a scarf!
It's done in a basic ribbed stitch - 2 knit, 2 purl.
I may have caught the bug - I've joined Ravelry (username jelliebeans), started crocheting a beanie hat with the leftover Rowan Damask, and have bought some acrylic yarn to make another scarf. As if I didn't have enough hobbies already . . .
