Colour colour colour in the first one half of the book, then from page 83 onward, there are no colour photos of the techniques and planning stages! Just when you need them the most to differentiate between very similar fabric patterns.
The code quilts are very interesting in that text is arranged as pattern ( in many different languages) opening some intriguing rabbit trails of discovery! As an abstract pattern "code quilts" could be fun and mysterious at the same time!
This book is inspirational to those of a textile/abstract bent however, anyone accustomed to lushly illustrated "quilting" books will be disappointed in this one; the photos are small with the story/narrative given the lion's share of the page. Some photos are fuzzy (p. 78) while the "digital graphics quilt" directions are very detailed (p.69-73).
All in all, an odd little book that is excellent in some areas, and quite deficient in others. "Great ideas" would sum up this book.
