This is a great book. Julie's philosophy matches my own so closely that I find myself smiling at her writing. She writes beautifully and meaningfully and manages to elevate polymer clay from pure technique to part of one's way of being. I share her joy in both learning and in passing on what I learn, and I am pleasantly surprised by how generous she is with her secrets. She describes her formula for "Jecru", a custom blend of clay she makes that she uses to enhance package colours, and shares her favourite colour palettes.
Her aim seems to be to spark your creativity, rather than encourage you to simply copy her projects, and I get the impression that she would be more pleased to see you create something uniquely yours, than to perfectly execute one of her designs.
The book focuses solely on one technique that Julie calls "imprinting". This is based on Mokume Gane. Throughout the book Julie also talks about colour and shares many colour palettes. For me it is this combination of elements that makes polymer clay fascinating, and the reason why I love this book. That we share the same way of thinking is only the icing on the cake.
If you want to go deeply into one technique and to create your own truly unique style, then this book is definitely one you will want to have in your collection. Highly recommended.
(Note that she uses the Sculpey Premo colour palette almost exclusively but refers occasionally to Fimo and Kato and gives her Jecru recipe in all three brands.)
