Another cute Christmas prezzy idea is a hot water bottle case. This is a nice gift because it is so easily personalised. Think of a person's fave colour, pet or hobby and I can guarantee there is a cute hot water bottle design that can come from it.
My mother in law is called Yvette and her favourite colour is green. This is what me and my hubby came up with for her and she seemed really chuffed with it when she unwrapped it.
