An excellent introduction, especially for those who are familiar with standard crochet but want to try Tunisian. "Complete" is, however, a bit of a reach. Because Tunisian crochet resembles knitting in the diversity of stitch patterns and sequences, a truly complete book would run to hundreds of pages. However, this covers the basics well and has some good exercises and sample patterns that work from beginner level well up to intermediate. Color changes, intarsia, and even entrelac are covered. Patterns are given both in text form and in charted forms for those who prefer that. (I do not.) If you can have only one book, this is a good start, but if you get into Tunisian seriously, you will want some of the more detailed and advanced titles.
