And the book I'd like to tell you about is:
Wendy Tait's Ready to Paint Watercolour Flowers.
The book provides tracings for each demonstration which you copy.
Then you follow the very clear instructions on what colours to mix and the techniques used to apply the paint so as to achieve a very good result.If you read and follow carefully, you get a very good painting.
This is one I painted from the book's demos.
Now, what I like best of all, was the fact that although there were 9 tracings, there are only instructions for 5.
This means you have to apply what you've learned in the demos you've done to create something beautiful without being spoon fed.
this is what I managed to do from a line drawing with no demo:
and this is one I created on my own, from the clematis which grows up the obelisk in my garden:
I really like this book. The tracings mean if you are short of inspiration for whatever reason, here is something you can draw and go...
and the clear instructions mean you can reproduce Wendy's painting in the first instance - and you should have learned enough by the end of it to produce a good work from just the line drawing.
Its only a short hop then to making your own line drawings - and totally original paintings.
Very highly recommended.
