Page 74 tab cast on is the basis to begin a triangular lace shawl. I love this style. You can continue with just the what it's call a yarn over basic shawl or get into the lace. I am knitting page  13 inflorescence shawl pattern. I have accumulated a lot of sock yarn, mostly cascade heritage, solid colors. I am using red for this shawl. I plan to use the 3 different blues in bands of color changes maybe 4 inches each light to dark like a colorwash. I am early in the category of intermediate knitter and feel this book a challenge yet possible. Starting in December knitting gifts for 2014 birthdays and Christmas. I am very pleased with the style this book is written in, easy to follow. Charts are written out, easier for Mr to do than the picture of a chart for me.
