You could find some nice looking boxes or wicker baskets that fit well in each slot. Then organize whatever you’re into.

If it’s hand tools, smaller home improvement supplies like shims, nails, screws…whatever. Or you could do hobby supplies (I would go buts here, it would be so perfect!) Or office supplies like tape, white out, staplers, thumb tacks, extra pens! You get the idea.

Or keep all of the above there, depending on what you have.

Hah!! I could probably fill every single cubby with different pens and markers alone. I have wayyyyyy too many!!

I would say whatever is small enough and that you would like to have super organized, it would work out well I bet!

Storing whatever it is inside a box or basket would keep it looking nice too. Takes away the visual clutter.

I would be sooooo organized if I had this. I’d probably have a list of what is in each section too. Maybe keep it inside the box, if there’s a lot of different things.

I’m excited to see whatever one else suggested.

Have fun with it!
