Thanks from me too! I have been searching for a pattern I can make over and over again (and not be bored by) for charity quilts and this was a great layout, punchy shapes full of energy, and you can really change up the look by clever colour choices in your fabrics. The book is available in digital form, really inexpensive and gives you 7 other patterns as well!
