Celebrate Opal at its most iconic with Best of Opal 4-ply — a joyful collection of re-released classics from some of Opal’s most-loved ranges.
These colour-ways span two decades of Opal design history, each originally launched between 2002 and 2018, and each chosen because knitters adored them then… and still do now.
Every ball is bursting with Opal’s signature striping magic: bright, playful runs of colour, rhythmic patterning, unexpected flashes and those nostalgic 2000s combinations we all recognise instantly. They knit up into socks that feel cheerful, uplifting and full of personality — like a little time-capsule from Opal’s design archive.
Made in Opal’s classic blend of 75% wool and 25% polyamide, this yarn is soft, sturdy, and machine-washable, perfect for everyday wear and gifting.

The Zwerger family formula is simple. Be the best at what they make, employ local families and train them to be the best. Putting sustainable production always as their highest priority. Supporting sheep farmers, ensuring all of the wool is ethically sourced and then adding colour, design and joy into every ball.
Back in the day the Zwerger family invented the process for mass producing self-striping wool. Today they are the leaders in global sock wool. Put both together, and yarns depicting the great painters of Europe like Hundertwasser, Van Gogh and others, self-stipe to make a masterpieces on your feet.
Why not sponsor a sheep that your Opal socks could come from with their Schafpate project?
