The little loops are for hanging, they just are not useful for hanging- my belief is that they are a survival from ancient times (pre WWII) when kilts weighed less than they do now, ie before 8 yards became the standard for civilians.

But the large loops! I was taught they are for the belt, not the sporran and that the sporran chain or strap is NEVER threaded through them! That's what we do here! Is there a concensus on this suddenly vital issue? Where does one go for the last word???
