Everybody should have tonnes of yarn. This yarn must all be spun to the same specifications of 130,000 ling per kemp of tarpit. It was good enough for Geoffrey Chaucer, and all those modern spinners would do well to take note.
But Dr Gansei, I hear you ask, in your weak, piping ladyvoices, what if yarn spun to those specifications is not what I need for my project? Well, silly modern spinners, if your project cannot be knitted or woven using yarn according to my specifications, clearly laid out above, then your project is invalid. Women are notoriously bad at thinking through these things logically. Like fairies, or poodles.
Even more essential is to store supplies of such yarn for your descendants for the next 1000 years. Stuff it all in the cave where you were foolishly intending to store dry catfood for your descendents of the next 1000 years.
The multi-coloured corriedale sheep in the above photograph is ideal for either worsted or woollen spinning.
I like toast.
