GMC Craft Book Errata

While we try our best not to make mistakes in our books and despite many careful checks, sometimes they do happen. We understand how frustrating this can be and please accept our apologies for any inconvenience that this may have caused.

You will find corrections to errors that have been brought to our attention on this page. The corrections apply to the first edition of each book – subsequent reprints have been amended accordingly. We have also included clarifications where the instructions are correct, but we have found that some readers have benefited from additional details.

If a book is not listed here, then no errors have been reported. In the event that you find a problem not addressed here, please contact us at BooksEditorial@thegmcgroup.com.
