After a few months of sitting on top of a sheephide makes it a bit sad looking. The fur is all flat and ugly and the feel is not very fresh anymore. Like in the picture below.
To make the sheephide fluffy and fresh again, it can be washed. I know it sounds weird to wash leather, but it works. I have always hand washed the sheephide, but I read from somewhere that it could be even washed in the washing machine, I guess with wool cycle.
I've washed this particular sheephide a few times and after the wash the sheephide looks amazing, like it's brand new. I have a quite cheap Ikea sheephide so for me trying this washing on the first place was not a big step. I'm afraid I have no picture of the finished product since I only washed it late last evening and the hide is still dripping wet. But I assure you it works, although I do not dare to suggest you to try this on your expensive cowhide rug.
