thanks for your post.
The book which is due out this month (might be out all ready) is a reprint of the first book on pastels that I ever wrote, called "Pastels Workshop". It is different from the Workbook, which is much more for beginners to pastels. It is a much bigger book, according to HarperCollins, the publishers, it is a "practical course in pastel painting", but instead of just seeing my work, you get to see the work of lots of other pastellists too. I have included projects of varying degrees of difficulty; demonstrations; practical tips and hints, and ideas and inspiration from varied subject matter, still life, flowers and gardens, landscapes, seascapes, figures, and there is even a chapter on abstractions. And there are chapters on the basic bricks and mortar of painting - tone, colour, space and perspective, composition etc.
It has been reprinted once all ready, and the second reprint sold out, so I was delighted to be informed that it is still considered "active" enough to deserve a third reprint. In paperback form this time.
If you cannot find it in the US, do let me know, and when I get some stock I can supply it.
