Ian Russell above, says, that "One thing I would say is that it does only deal with a single aspect of watercolour." ...Well, the title of the book is 10-Minute Watercolours, what can be done in 10 minutes? A sketch... if you want something more advanced, you'll have to get another book... There are so many books on the market for various stages of development. In my opinion, this is a very useful book for beginners and slightly more advanced amateurs alike.
My only criticism is that the format IS too small. A5 would have been much better, so some of those illustrations that are 'double spread' in this format, could have been printed onto one page.
Otherwise I agree with the previous reviewer that, yes, this is a little
Gem of a book, which is extremely useful and full of easy to follow tips. I highly recommend this book to anyone, especially if you are, like me, coming back to painting after a good few years away from the brushes...
