I started in June 2009 and I am at my #10 now Why am I doing this? 1. It's a safe playground, working on a wtj gives myself the message: it's ALL RIGHT, mistakes are impossible, everything is allowed and the right way to do it 2. I don't know a better workbook, paper quality, cover, size, everything is great! So I stick to that (and it's not printed in China like e.g. moleskine are!) 3.. The instructions are part of the game, although I do not follow most of them since I started the second one 4. I don't know any book that could be more fun than this- so thanks to Keri Smith! Will I ever stop? I believe not. If you want to know what's inside, please look at the sets.
