I think I found the bunny, but I do not know if there are any pattern corrections anywhere.
is this the bunny you talk of?
The link goes to Ravelry. If you are not a member: you need to sign up to see the link but it is free, fun and useful, so I recommend it.
you can see on ravelry that 123 projects have been made. SO there are a lot of knitter out there that have made the same bunny. Maybe they can help you?
Or you just post the lines you have problems with.
