Erratum
Whenever I publish errata, I also update the .pdf available for download. At the same time, I generally email everyone who has previously purchased the pattern with the new version, so that their copies are up to date.
However, I inevitably get a number of error messages and bouncebacks, so not everyone gets their new copy. If you have a version of a pattern which does not have its errors corrected, and you would like one, contact me with details of your original purchase and I will send you the latest.
