What do I do with an enormous sketchbook?

My daughter gave me this very large sketchbook which she got from an art shop in Dunedin, (sadly they've gone out of supplying these now, and I find it difficult to source sketchbooks which have high gsm papers suitable for watercolour). It is quite large, a bit too big to take out sketching, so I decided to use it for watercolour paintings instead. This was then a little intimidating, especially the first page as you want it to look good!

Here is the result: 

 Shell Study. Watercolour. The first page in my large watercolour sketchbook.
