We've just home slaughtered our first lamb, and as he was our first, I don't want to waste a thing!
Hence the offal sitting in the fridge for haggis, the stomachs soaking in brine for tripe for the dog, and am working the sheepskin into a lovely rug

I researched quite a bit before the day, so as to be ready. Bushcraft.co.uk has quite a few discussions on tanning, mostly deerskins, but certainly sheep too.
They have recipes for chemical tanning, brain tanning or using eggs (quite useful for smallholders I'd have thought!)
I'm going for the brain tanning since it was home slaughter and available.
Currently I'm fleshing the skin today - using a blunt axe while the skin is stretched in the frame, it seems to be working well, with a sharp knife for the odd stubborn bit.
My next step will be working in the brain for tanning, and it looks like it's perfectly fine to do it from the one side so as to leave fleece on.
Then it needs working, stretching and rubbing the brain in for a long time until the entire hide is dry, soft and supple.
Then it will be smoked so as to retain the suppleness, and finally washed to take out the smoke and dirt.

it's worth it, as this is supposed to be my week of holidays lol
Will post pictures as I go along.
