I have this thing about loo paper: it has to be really nice. But some that you think would be nice, aren't.
For example, Andrex loo paper, really isn't that nice. Although the cute little puppies somehow deceive you.
Velvet is lovely. Really soft, quilted - bang on.
The one i'm dying to try is Charmin Ultra, now i know what i said about the puppies and their deception where Andrex is concerned, but those bears would never lie, i'm sure of it.
In the end, I don't think you can go wrong as long as you don't buy supermarket's own. Loo paper is something you can afford to be choosey about.
