Testing Colouring book - mini mandala

Animated GIF for some steps I've played with a mini mandala colouring book.

This is my third one. Page 2.
Before this, I had done two others.
The 1st one I use felt-tip pens. Ok.
The 2nd one I use wooden coloured pencils. Not quite.
The 3rd one this one I use water-soluble coloured pencils.
The paper cannot stand the water...
ooops.

Hint:

1. If you would like to enjoy colouring,
do not buy or use cheap colouring materials.
Really good ones.
Even Derwemt Inktense is not good enough.

2. Depends on the size, mini ones are quicker to finish.
The size of this colouring book is 12 cm x 12 cm.

But the colours can easily go outside the black lines.

3. Colour Therapy?
It has been said that it is therapeutic.
At least for mindfulness,
it put your mind off other matters..
But if you have art & design training before,
the mind become so busy planning designing...
choosing colour schemes, etc....
ooops.
