She probably has bidets installed in all the palaces and castles that she regularly uses and so would not need any sort of paper roll or reusable cloth to clean herself, instead using a towel to dry herself. If that's not the case, then in all likelihood she has toilet rolls made by appointment under the Royal Warrants system.
I can't for the life of me understand this apparent obsession with the Queen's personal hygiene. I'd suggest she uses pretty much what we use (athough perhaps not the discounted loo rolls in most major supermarkets?).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
