This sock pattern was designed for the Sock Knitters Anonymous group on Ravelry as the July 2025 Mystery Sock (or MOCK) to fit the featured theme ‘Art & Music’.

The inspiration for these socks was the symphonic poem ‘The Moldau’ (also known by its Czech name ‘Vltava’), one of my favourite classical music pieces.

The pattern is divided into a series of four clues to be released on July 1, 8, 15 and 22 of 2025. Because it is designed as a mystery no photos of the finished socks are present on the pattern page or in any of the clues. Please use a spoiler image as the first photo of your Ravelry project page if knitting along in the MKAL.
