Well, the sketchbook is actually a year old - it's a Fabriano handmade watercolour paper book I bought in Venice last year. I had great hopes for this book, but it's going to be a lot more challenging than I anticipated - the paper is very rough and watercolour behaves very strangely on it - it's like it sits on top of it and takes forever to absorb. Fine if you want to do a lot of rework I guess. Not so good if you want a quick sketch and turn the page!!
And I found it almost impossible to draw with a fountain pen - the roughness of the paper made it a very scratchy experience.
But no doubt I will find a good use for it all the same - it just needs more experimentation!
