And one fan has described it as a 'good hobby' to have and tweeted, "Any time you send a card to the Royals you will receive a response. I have a couple of the birthday cards thank you pictures from Prince George and a thank you card from the Queen when Phillip died. A good honest hobby if you are a monarchist."
