I have a terrible track record as a test knitter, but @heybrownberry's R and R socks might just have cured my affliction (I may be speaking too soon...)
Image description: two cakes of Tukuwool sock yarn, one soft pink and one dark brown, next to a sock-in-progress. The sock is happening toe up, magic loop, and I'm just about to turn the heel. Yes it's still the first sock, but aren't I allowed to get excited?! The beautiful texture combines my two colours, and lives up to the pattern's name, being extremely relaxing to knit. Also in the picture is my wooden acorn full of stitch markers from @amirisushop, and a few real acorns gathered on a dog walk.
