self-help book for drawing skills

If you want Disney characters this should help:

It has some good reviews and sounds like some books that we had when the children were small. These started with a circle that you draw two ellipses over as if they are equator and a longitude. You can draw this at any turned angle and the book showed how to draw the face relative to these guides so the head is turned to the angle of your choice. You can create a recognisable Winnie the Pooh or Tigger quite easily.

RobinD, is getting used enough or should the book be new?

A used one should be OK. Certainly with the Mark Linley one as there isn't anywhere to draw in it. It's not one of those where you complete the picture. It shows you what to draw in a few stages and you copy onto your own paper.
The Disney ones we had were the same, no drawing in the book. What we had were individual books for each character, one for Tigger, one for Pooh etc. We got them from a Disney shop and they weren't very cheap, but they were good.
I think it's the Mark Linley one that starts by saying 'if you can write you can draw' and explains that you can already use all the tools you need.

If Amazon lets you view this it shows you a few pages of the Mark Linley book, to give you an idea of the content before you spend your money :7)

grr, link didn't work. Just under the picture of the book there is a link to 'Search inside another edition of this book' It shows just a few pages, but gives you some idea.

thanks very much Robin.
