LOL, Why do you keep junk?
Personally I have great organizing skills.
I don't keep junk but I do keep odds & ends which come in handy from time to time.
I use bins and plastic stacking drawer units which I can add to and have tray dividers.
Here are some ideas...
If you are limited for space you might have a look at Pinterest on a search for small spaces storage.
I picked up some plastic trays at Walmart which have plastic dividers and lids.
You can also search pinterest for pantry organizers which may give you an idea for option you haven't thought of yet.
When I had a garage and a basement I used old pickle jars with the lids nailed to the bottom of a shelf to hold hardware and little stuff.
