Patchwork Flower Lessons
It would be tough to find a more thorough book on patchwork than this one! Not only does it feature loads of cute patchwork patterns, but it also includes perfectly photographed, step-by-step instructions and diagrams to walk you through any tricky bits along the way.
Note that the book is written in Japanese, but patterns and schematics are included. Crafters who cannot read Japanese but who have some sewing experience are usually able to interpret the instructions without any trouble, and others can use the projects as inspiration for their own creations.
