Using this book is easy. Just pick the shawl pattern you like based on the moon phase that inspires you. Start knitting or crocheting following the instructions in the book. When you're done, you'll have a unique shawl. As for maintenance, gently hand - wash your shawl in cool water with mild detergent. Don't wring it out, just press out the excess water. Lay it flat to dry. Also, keep it away from sharp objects to avoid snags. Have fun creating your moon - inspired shawls!
