The trick to a casual, carefree picture wall is to find the right balance of order and chaos. Uniform spacing between the frames and a consistent frame and matting colour are good places to start. In our private study project, we kept the strongest coloured artwork in the centre to provide a visual anchor as well. To give it a bit of subtle interest, we varied the frame widths and depths and framed one in black to help incorporate the wall lamps. The most important thing though: start with art and photos you love!
