Since 1997, the charity Fine Cell Work has been teaching British prisoners creative needlework. Now these stitchers, 95% of whom are men, have collaborated with eight artists, including Ai Weiwei and Cornelia Parker, to create artworks to appear in an exhibition and auction at Sotheby’s called Human Touch.

Human Touch is at Sotheby’s, London W1, from 26 February to 3 March.
