I learned a lot about teabag folding and card making from this easy to use book, but to be able to make many of the cards in the book, you also need a fair amount of rubber stamping kit, as one of the author's specialities is creating beautifully printed papers with stamps and inks. I was disappointed when I found out how much this equipment costs, which is why I've given the book only 4 stars, even though the teabag info is excellent.
I'd like to add, nearly 3 years later, that I did end up buying rubber stamping equipment and going to classes. Last summer I attempted the most complex project in this book, as a challenge, and the result was amazing, and highly praised! So this book works at different levels: you can use it with or without the stamping kit, but some of the projects can't be undertaken without stamping gear.
Be aware also that new techniques and tools have come on the market since this book was written, so there's sometimes an easier (but more expensive!) way of doing something suggested. Adhesives in particular have come a long way since the days of double-sided sticky tape that takes ages to peel.
I still love this book because it's so comprehensive and yet so simple to understand.
