Back in 1989, renowned knitwear designer Ruth Herring co-created Knitting Wildlife, a book of wildlife-themed patterns that helped raise vital funds for conservation. Inspired by those original designs, Ruth has re-imagined the collection for 2025, bringing retro charm into modern, wearable knitwear.
These vintage-inspired, wildlife-themed patterns, including patterns for a penguin sweater, are free to download, with an optional donation to support WWF’s global conservation work.
