I have just emptied my loft and discovered that my idea when we last moved in 2015 has been invaluable!
On every box I listed the contents on a piece of brightly coloured paper and stuck it on the outside along with the date(which was in big letters in black marker pen) . It sounds so simple but when you’re moving yet again (like me!) or just sorting out it saves so much time as it’s easy to spot which boxes don’t need sorting or repacking!
