Worn pebbles, shifting light, and the rhythm of the tide – Petra socks are inspired by ancient places softened by time. Echoing the quiet beauty of smooth stone and weathered paths, they
offer a timeless, soothing knit.

Knitted from the toe up and featuring entertainment round after round, Petra is a cosy sock that hugs your foot with its pebble-like motif, framed with a light rib. Her comfy heel flap gives a
snug fit, and her twisted stitches add a graceful finish.

Including charts and written instructions, Petra is all the entertainment your hands – and your feet – desire, and is perfect for both confident and adventurous sock knitters alike.
