I nearly called this post "Smack Upside the Head" or "Duh". Why I didn't think of looking for the errata for this book I can't imagine. Head to the publisher's web site and there it is, a pdf ready to download. And confirmation of the flubs in all 3 charts, and a bunch of fixes for text that describes the armholes and armhole steeks. Goodness, am I glad I found this before I got any further!
So--lesson learned. Check for errata before beginning a complex project. This should tone down the dialogue a good deal, but it's still no substitute for thinking through the instructions of a pattern and having a little mental chat with the designer anyway.
And take a look--I'm out of the border and into the main pattern!
