When there is a case of errors in Printed Instructions, it is the responsibility of the Publisher (whether a magazine, or a company printing & selling commercial Patterns) to publish and "ERRATA" in their magazine or on their website. Have you tried to go to the website of Fons & Porter and seek their published information? The place to look in the magazines would be a month or two AFTER the date of the issue showing the pattern in question. I hope this makes sense. You might try a google search.
