We've all done it. Don't even try and deny it - you go to wrap a gift, cut the paper and realise it just falls short of covering the entire present.
This morning Waterstones tweeted a short - like, really short - video about how to wrap a present and it's already making people's jaws drop.
Instead of throwing the paper away in a huff, or assigning it to a smaller gift, just turn the pressie diagonally!
Watch the video below and go home and practise tonight.
It'll save you a heck of a lot on wasted paper and anger management classes too.
Here are some of the reactions on Twitter to the video that will change your gift-wrapping life.
So if you fancy turning your hand to wrapping presents and aren't very good at guessing the size of the piece you need to cut, you'll be fine this year.
