The errata have already been included in the current version.

A hot water bottle really helps keep you cozy at night, especially if you have a tendency to cold feet.
This comfy cover will protect you from the heat, and is nicer to the touch than rubber!
The cover is styled with a turtleneck and a drawstring bottom. The lively and colorful jelly bean design will give the knitter enough of a challenge to keep it interesting and will make the cover pretty enough to give as a gift.
