Aunty Biscuit is knitting a prototype tail.  This is for the sheep which currently resembles a cloud.  As most sheep have their tails docked when they are lambs, compounded by the fact that they spend most of the year covered in wool there isn't a lot of shaping to contend with,  It seems to be more about size and proportion.  You can get fat tailed sheep (I kid you not) so that should give her a bit of leeway.  Mum meanwhile is working on a graph.  I initially misheard and was a bit concerned as to how long the neck would have to be until it was explained to me that a graph is little squares on paper and not some acacia leaf eating African mammal.  Glad that's cleared up then.
