I can appreciate the reactions of all the reviewers here - this is a book to cause strong reactions. It is a pity there is no 'Look Inside' feature. If you are considering purchase, be aware these are indeed simple styles, making them easy to draft and to make up, and to modify to suit yourself. But they are all fairly loose, often with front and back bodice the same, no dart shaping, no curved armholes, rather like Muji clothing meets Very Easy Vogue. They suit being made up in natural fibres, but will often suit a bold print or stripe as well as a plain fabric. There are not 25 different designs here, more like two-thirds that number, plus close variations.
I hope that helps you decide if the book might work for you!
I was intrigued, and have already made a couple of toiles (trial garments in muslin to check the shape and fit). The drafting was straightforward, though presented in a way new to me - as combined diagrams to construct the pattern and fabric cutting layouts. You need to concentrate, and look out for odd inaccuracies which I suspect are the result of converting cm/inches. The patterns I tried made up accurately, and the sizing was what I expected. I definitely think they have potential for simple summer tops, tunics and dresses, but I do plan to modify them to achieve a look and fit that suits my style.
