Ten different shawls are divided into chapters based on shaping and construction techniques, teaching concepts in a fresh new way. You'll use not only diagrams and charts but also mathematical means of keeping your designs in line. Ever wonder why your stitch count is off on another pattern? Anna will show you what deltas are, how they work, and much more in this extraordinary book.
