This book is amazing. I find most knitting books are mainly patterns without teaching you different techniques, but in Superstar about half the book is teaching followed by patterns directly related to what you have learned.
I am quite an experienced knitter and I hate getting a new knitting book and having to read through the first 3 chapters which tell me what I already know. This book starts at the place most confident knitters are at. Once you've learned the basics- k, p, co, wrap etc this book is great to take you to the next step.
