Ideally, it would help if you started packing when you realized you were going to move. In some cases, you might only get the notice of a move a few weeks in advance of it. If you’re planning the move yourself, the ideal thing would be to start packing a month before you have to leave your house or apartment. This suggestion doesn’t include the stuff you use regularly but the things that are packed away. Seasonal items like Christmas decorations and curtains may be the first things you should pack since it’s unlikely you’ll need to use them soon. From there, you should work down the priority order, with the essential items being packed last.
