This book and DVD Spin Art: Mastering the Craft of Spinning Textured Yarn
was recommended to me by a spinning collegue and how right she was to do so.
By working through the book you build up skills and techniques like building blocks.
The pictoral, written and DVD instructions are all clear and precise taking you through the techniques step by step.
By following Jacey Boggs excellent tutorials I was able to produce an art yarn on my first attempt.
It would be useful to have the basic knowledge of spinning, how your wheel works, how twist is made, balanced yarn etc but I'm sure an adventurous beginner would have no difficulty following JB's instructions.
