The UK Hyperbolic Crochet Coral Reef, presented in partnership with the Crafts Council, is a large-scale art work that consists of thousands of brightly coloured crocheted coral, created by craft makers all around the world.

The reef grows as it tours; participants at each location learn to crochet and add their coral to the reef.

The crocheted reef is a fusion of traditional craft techniques and experimental crochet using recycled materials such as plastic bags and wire.

All the sections are models of hyperbolic planes, a geometric pattern resembling real coral, made by increasing the stitches on each row of crochet in equal numbers.
