For what it's worth, I found myself with a lot of 'trimmings' having butchered pigs, and although I had skins, I didn't realise how utterly impossible they are to stuff without the right kit.
My solution? Make them skinless, simply roll the prepped sausage meat (with various flavourings; chilli, onion garlic, leek etc) into 'sausages' and freeze.
Never tasted a sausage like it!
