The largest crochet blanket measures 3,377 m² (36,349.58 ft²) and was achieved by 67 Blankets for Nelson Mandela Day (South Africa), at the Union Buildings in Pretoria, Gauteng, South Africa, on 21 April 2015.
Carolyn Steyn, founder of the charity 67 Blankets for Nelson Mandela Day, brought together communities and charities from across South Africa to participate in this mammoth Guinness World Records attempt. The blanket was made up of over four thousand individual blankets, hand-crocheted by thousands of people from communities across South Africa including Diepsloot, Alexandra and Cosmo City. Huge numbers of school children, the Ga Rankuwa 'Golden Grannies' and inmates at Zonderwater Maximum Security prison and Leeukop Prison Juvenile Centre came together to help craft the largest crochet blanket in the world.
Each individual blanket that helped to create the largest crochet blanket will be donated to families in need across South Africa.
