I have complained bitterly about the lack of a good colour range in DK weight pure wool, so I'm really pleased with the new Rowan Pure Wool DK. I bought one ball in a few of the colours, purely in the interests of research, you understand.
The yarn feels soft and non-scratchy and the colour range isn't bad at all. Colours in the photo are rather washed out - they're brighter in real life. Decent yardage too; 125m (136yds) in a 50g ball for £3.25.
