I dug out the 2008 books and sure enough discovered that it had started there. Tonight I found my favourites and have scanned them and put them all together...
The four on the left are 2013 drawings and the three on the right are 2008. The sketchbook I'm using this year likes watercolour / watercolour pencils a lot more than the 2008 book, the water used to stay on the surface and dry in an odd way! So I used to just stick to the watercolour pencils without the water.
