This is a very well written Book with many good illustrations. The ring binder down the spine is great because you can lay the book completely flat and this helps when following instructions of a new craft. All the instructions are very clear but the American/English terminology are right at the back of the book so check this out before you start with the wrong stitches. There is also a fold out page at the back as a quick reference guide to working the mesh size that you want which is very helpful. All the patterns provided are great - so many different topics, and you can easily work out how to make your own. This book has everything you need to learn how to do filet crochet.
I have never tried filet crochet and this book has very clear instructions and is full of inspiration. There are pictures and patterns for each project and the wire ring binder makes it easy to read while crocheting. The only thing I would say are some of the photos are a bit pale (white background with pale colour crochet on top) but i would highly recommend this book.
