No one like the smells of ash and dottle, so I have always assumed that my practice -- dumping it into an empty large tobacco tin with a tight lid (preferably one of those with a plastic top), then throwing away the tin when full -- is universal.
But I have learned there is endless variety hereabouts and so, I ask: Where do you stick your ash?
