What is the most efficient way to use toilet roll?? fold it or scrunch it??
I prefer to fold it in a rolling style then if there's not too much on it I can fold it in half and use it again?
Make sure you wash your hands after.
Flatten it and stack them like dollar bills in a nice tight rectangle.
How old are you that you haven't worked this out for yourself yet?
LoL... ewwwww. I like to roll mine in long layers.
