I found this book really cool and the amigurumi dolls are very cute (hence the title) but i found the actual patterns rather confusing. Annie Obaachan's rendition of a DC (double crochet) is actually a SC (single crochet) even the picture diagram shows a SC as a DC stitch.
This book in my opinion would best suit an advanced beginner or intermediate level craftsperson – just because of the pattern confusion.
