Jo is fascinated by mark-making and her process involves building multiple layers, using a wide range of materials and techniques. She particularly likes drawing back through layers of paint; sometimes using an electric sander or glass paper, bradawls, silicone wedges and etching needles.
Paintings usually start from studies, thumbnail drawings, colour swatches and notes in her painting notebooks/sketchbooks. She takes a lot of photographs, but in practice only use them occasionally to jog a memory or to check tonal contrast.
