Okay, we've settled the sheep classes and I'll get the show online tomorrow. We've gone for:
Cutest lamb (or wittle wam

)
Most impressive horns
Wooliest sheep
We'll also have a Smallholding DIY show, suggestions for classes much appreciated.

And no, helping out won't prevent you from entering, unless you suggest a class for "best X owned by members with Beautiful South derived usernames"...

(I've been listening to them all week since you mentioned it.)
