This book teaches you how to use colour in Torchon bobbin lace, with 64 patterns and variations. It covers simple grounds, headsides (fans and scallops), footsides, shapes such as diamonds and zigzags, rose ground and spiders. There are explanations for further ideas, including adapting existing patterns for colour, and a section about colour theory.
Jo does all the hard word in advance, showing you what incorporating coloring does to your pattern, how to do it, and what pitfalls to avoid. Absolutely excellent, simple but brilliant to get the knowledge in your head. Thank you Jo!
