Something else I have started doing again is colouring. Using different tool, colour pencils, felted pens an water colour pens. I will try again water colouring as well.
I have plenty of different colouring books to choose from, including some really annoying ones that are printed double sided. What were they thinking? Felted pens with colour through and colour pencils will copy colour onto the other page unless you waste an extra clean sheet of paper for every page. Really wasteful. Some are bound really idiotic as well.
