I think you should line the pieces of art along the floor and take good pix so we know what you have to work with. Does the art echo the contents of the cabinet?

You have a great opportunity here for a gallery of art, photography or a combination of bother.

I would remove the tall cabinet, it is blocking the sight line down the hall. You could line both sides with artwork or if the hall is long enough which it looks like it is, you can break up the hall space with a console table or stagger 2 of them. You need some good lighting on the artwork.

Here is a few links for ideas:

If your hall is wide, you can hang art on both sides. Beside the curio cabinet or over a console would be
appropriate, but you can hang a grouping anywhere.
In a narrow hall, I would hang art on only one side, preferably at eye level to an average adult.

I love art on the wall. But I don't think this hallway is the best place for cabinet. It really can't be seen properly. Do you have another location?

the cabinet does not work in the hallway. I would place the art on one wall if the are small frames. if the art is very big,
I would do both walls. hard to decide without seeing it

We live in a smaller house than our previous home so there's no other place for this curio cabinet. We have a lot antique furniture, with four pieces in my garage as it is, so no new furniture (and we have no new furniture except our bed). We won't be staying this house for a long time so buying a new piece that we don't know will work in another house isn't cost effective.

I'll play around with it and see what works. Thanks.

IMO art will always work no matter where you go, but I want to know why the cabinet is there and also why it can’t be moved from its center location. I actully think it closes in the hallway and really makes no sense where it is. I also do not love art collages IMO it takes away from each piece.

Does the cabinet have lighting? If so, move it in front of one of the outlets so you can plug it in.
