As Carolyn commented it depends on what you are trying to achieve. For the rest of the page I took Gwen´s advice for colouring and used my pencils first and water with a brush second.
Lessons I learnt this time around (adding to yesterday´s list):
*Don´t be tempted to go with the same brush from one colour to another, even if it is a very pale yellow. It will blend, or even worse muck.
*It is quite useful to have one glass with water to clean the brush, a cloth to dry it and another glass with clear water for the following colour.
