Trial and error

It’s good to follow the rules of whatever medium you use, but there’s nothing wrong with stepping outside of the box if it means achieving the effect you want. Remember when I said that using a certain type of eraser works better than the other? You may find that using a rubber eraser actually gives the best result for you. Or using watercolour over coloured pencil looks better. Whatever it is, trial and error will occur when you step outside of that box. But don’t be intimidated! The process is entirely fun.
