This bright piece is by Cheltenham-based K8TB or Katy Barnfield. K8TB specialises in working with carbon fibre to produce her artworks. Together with Terry Barnfield, she works on carbon fibre commissions from their website.
K8TB volunteers for the Stop Bullying Project in Cheltenham and she does this with artist Lee Crew. Together they raise awareness of bullying and organise hundreds of artists from all over the world to personalise standard issue school exercise books. What is not clear to me is whether this was a collaboration between the two or just K8TB alone.
