In traditional Scottish dress, the sporran basically serves as a purse for a kilt-wearing man that doesn't have any pockets to stash his stuff. It's a small bag suspended by a chain or cord around the waist, generally made out of leather, hair, or some kind of fur. They can be fairly simple or complexly decorated, as the styles below with engraved metal frames and metallic tassels.
Kate MacPherson has been a taxidermist and sporran-maker for over 20 years in Scotland and finds her materials mostly as roadkill. She has been criticized in the past by various animal- rights campaigners for misusing animals, but I personally find her manner of turning roadkill into sporrans an interesting way of recycling and animal that is already dead and giving it some new purpose. These bags may not be for everyone, but they certainly are interesting. See more HERE.
