Thinking of a sheep skin seat cover? You may already know this but I did not until yesterday. In the equine world there is such a thing as saddle cushions. They're meant to make a saddle more comfortable for the horse as they fit between the saddle and a blanket on the horse's back.

They are sturdier than most sheep skin blankets and have finished edges. And they make great seat covers for motorcycles. Just bought one today for $40. Still going to have to figure out how to best secure it. Any ideas?
