Have a space for everything
Make this as general or as specific as you like.
Small stuff together, big things together, children’s things together, etc.
Use lots of dividers!
You can use an old cutlery tray, the bottoms of cereal boxes, etc.
Clear it out regularly
I like to put a bit of masking tape in the corner with the date when I last organised the drawer. This will also help if you have unidentified keys – you know if you’ve had them there for 6 months that you probably won’t use them ever again, so you can throw away.
How do you organise your junk drawer?
