The 37-year-old and a number of other designers including Jonathan Saunders, Holly Fulton and Zandra Rhodes have designed a new bank note in a bid to try to keep the facility, one of Britain's leading print factories, from shutting.
The works of art will be sold in an attempt to raise the £200,000 needed to keep the company open next year after its funding was cut.
The former Spice Girl told Vogue.co.uk: 'I am proud that my business is based in London and it is important that we nurture the skills and talent within the British fashion industry.
'The London Printworks is one of the few remaining facilities in the UK that offers the opportunity to create bespoke textiles and their great work has to be supported.'
