And the last mark has been made! (Can you spot yours?) Thanks to everyone who came down and took part in Roanna's piece. There are the individual marks of more than 250 people here blended in (or standing out from) Roanna's careful lines. A study in tone, collaboration, uniformity and relinquishing control.

The gallery will now be closed until Peter Griffiths exhibition 'The Plant Room' opening on 12th September.

Our Ways of Making exhibitions form part of Making Ways, a new programme supported by Sheffield Culture Consortium through Arts Council England to showcase, celebrate and develop the exceptional contemporary visual art produced in the city.
