Jumper knitted from the first fleece of the sheep named 'Dolly' which was the first animal to be born as a result of cloning an adult cell, design Holly Wharton, by the winner of a competition 'Do a Design for Dolly' and made by Steve Melia, at the School of Textiles, Leeds University, 1997

This jumper was made from the first fleece of ‘Dolly’ the sheep, the first mammal to be cloned from an adult cell, who was born on 5 July 1996. After Dolly's shear, 2.7kg of her fleece was donated to the Cystic Fibrosis Trust to raise funds for research. Dolly was cloned at the Roslin Institute in Edinburgh, Scotland. Continued research at the Roslin looks at the possibilities of gene therapies for the causes of cystic fibrosis.

In September 1997, a competition called 'Do a Design for Dolly' by the Cystic Fibrosis Trust and supported by Portman Building Society. BBC programme The Clothes Show launched the competition. Donations to the CF Trust were lso welcomed.

In March the following year, a 12-year-old girl, Holly, was announced as the winner. The only stipulation was that the design needed to include the CF Trust logo. The jumper was presented to the Science Museum at the start of National Science Week in 1998.

Sheep usually live to around 11 or 12 years of age, but Dolly was put down on 14 February 2003 when aged six after having a progressive lung disease.
