These Magic Whiteboards (cheaper on Amazon )are crazy useful if you are managing a lot of people and you don’t want notices all over your house. We cut them up and put them on the inside of cupboard doors. You don’t need any screws or anything, they just cling to a flat surface. We use ours for medication charts, checklists, stock checks, drawing out quick diagrams or guides for new people - all kinds of stuff. Carers can leave notes for each other or I can leave notes for them, all behind closed doors and private. We bought a roll about five years ago and it’s still going strong.
