Hi Andy. OK I've voted and that makes 11 of us

. I have put Hebridean but in fact I would do the cross the other way around so that I would put a Suffolk cross tup to Heb ewes - they are milky, thrifty, long-lived and excellent mothers who can raise large crossbred twin lambs for the meat trade, with meat which is leaner and tastier than the Suffolks. The cross gives white, tight wool so the skins are excellent for tanning.
For skins at the abattoir, they usually sell them to fellmongers (I think that's what they are called) and they get a fair bit for them. Or at least that was the case, but most skins went to Russia and I believe that trade has dwindled recently. I once got a cheque for my skins (I think about £5 each) but had to return it as I get mine back and send them to Fenland for tanning. So clearly the money came back to the owner, or at least some of it. I've no idea what happens now. Some abattoirs may have brine baths in which they can soak your skins for you, but if not you must collect them almost as soon as the sheep have been killed, rush home and salt them straight away, otherwise the wool slips. I can give you the details of how to salt skins if you want.
