Tips/packing hacks for moving house?

[GreenCaterpillarOnALeaf]

My DN is moving into her first flat next week! I am helping her but to be honest I’ve never been very good at packing and moving I’ve generally just shoved all my shit in a box and dumped it in the car.

Any “hacks” or tips for moving would be greatly appreciated, even if it seems basic and obvious. We are probably going to hire a van as I don’t think my Fiat 500 is the best car for the job.

Honestly? If you can afford it, hire professional movers. I've done it both ways and doing it yourself with a van is infinitely more stressful than having a team of movers turn up and do it for you. Having a massive declutter and getting rid of stuff before moving day definitely helps too.
