I say over the top but my wife thinks it should go the other way. Just depends on who uses the last of the roll as how it gets loaded. I usually turn it around if my wife loads it.
Not a problem at my house we dont put it on the roll don't even own a roller. We both hate them. We just leave the roll on top of the pot. Makes the paperwork easier!!!!
No kiddin' Upstate. Sharing a square is a female rule of decency. No matter if it's a stranger in public stalls or an un-favorite co-worker. We just don't let sisters drip dry.
