I was privileged to have studied the Mo-Ku Ink Splash technique run by a master painter and her daughter and to this day feel so privileged to have learnt from such wise, patient, encouraging, forgiving, accepting teachers. This is a very specific process using water colours (another firm favourite of mine) and is very difficult to master. In fact, it takes years of constant practice. You have to be organized, prepared, plan carefully, have incredible patience and often apply many layers of paint and only after that, apparent randomness occurs. (I still have a long way to go, but was very happy with these results).
