The bendable blocking wires were perfect for the round shapes.
The pattern also has the knitter go up a needle size somewhere in this section. I didn't. It also has the knitter going up a needle size in Chart B on and again in Chart C. I only went up a needle size once, when I was starting Chart C.
Another thing I like about this pattern is the L O N G garter stitch tab (34 rows/17 ridges) used to start the shawl. This avoids the strange peak that often occurs in crescent shawls.
