The largest crochet blanket is 17,188.57 m² (185,016 ft²) and was made by 67 Blankets for Nelson Mandela Day, the Department of Correctional Services and the Nelson Mandela Foundation (all South Africa), as measured in Western Cape, South Africa, on 22 April 2016.

The blanket was crocheted with the help of around 1,500 inmates from 30 correctional centres across South Africa.

The final assembly and measurement was carried out at Drakenstein Correctional Centre, which was formerly known as Victor Verster Prison. Nelson Mandela was moved here where he lived in a private house inside the prison compound before being released.
