A very useful book - not a big book, but it concentrates on painting flowers using coloured pencils. The author mainly uses Faber-Castell Polychromos (but also some Prismacolor) (NOT watercolour pencils!). UK based but has a useful address register for both UK and US dealers, websites etc. I would say book is equally useful for semi-beginners and skilled artists.
Even though I am fairly skilled at drawing myself, I just love this book - inspiring, and takes me right back to my childhood. I am sure I will become totally stessfree and relaxed with it, though I can hardly bear to start colouring - it's so pretty! A great find for a creative adult or teen - not for young children, as the drawings are very detailed.
