Offcuts of upholstery fabric (Patchway BS34)

Hi all, I want to learn upholstery & have bought a few old dining chairs to practice on before I tackle more difficult tasks. I'm looking for some offcuts of upholstery fabric, they don't need to be very big. Any size from 0.4m x 0.4m will do. As all the chairs are different, the offcuts can be any colour or design. Hopefully someone can help me. I'm in Patchway but am happy to collect from other areas. Thanks in advance.
