These socks are very cozy! The wide ribs on the shaft flow into a tendril pattern which runs diagonally across the back of the foot. The artful leaf tendril is far too beautiful to hide in shoes, so we recommend this pattern for fine sofa socks made out of the wonderfully soft REGIA PREMIUM Merino Yak. The instruction contains the information for sizes 40/41 and 42/43 and how to round the socks on two circular needles.
