Please give your best organisation tips!

[2021ComeAtMe]

So after discussions with DH we've agreed stay in our current house for the next 5-10 years, by which time we'll have outgrown it and will look for somewhere bigger.

But in order to stay here for that amount of time I still need some great storage/organisation tips! Every room is still to be finished so I don't mind buying things that can be recommended (especially for the kitchen as it's only very small.)

We're all pretty good for de-cluttering
Thanks.

There was a thread yesterday about making use of the space under kitchen cabinets, using drawers where the kick boards are. Really handy for things like trays, baking trays etc.
I've also read about having hinges on bath panels so you can store cleaning products in the empty space around baths.

I cleared out our kitchen food cabinets last year and bought loads of Lock & Lock storage boxes. Instead of half empty bags of sugar and flour falling out everything now lives in a L&L box. I bought a Brother labelling machine so each box is neatly labelled.

As a person who is terribly disorganized but has read many many articles on becoming organized - de clutter.
