The Corsica pattern errata has just been updated both at FiberFiend.com and on Ravelry. If you purchased the pattern as a Ravelry download you should have automatically received a link to download the updated version.
In other news, be on the lookout for Esmerelda Part 6, the Right Sleeve, in the next few days! I just worked the last decrease on my sample’s right sleeve, so hopefully I’ll get in a photo to show you as well.
