how do you get bigger bags of different sizes like that?

How did you get the icon up there?

if you mean the Pot Icon near the ceiling on the first floor, I think it's sitting on top of the SDB, but most items sit on top of them with a bit of space as if floating.

You can make things float if you drag a furniture item with stuff on it back to your inventory (I think that's how I did it)

What Sauce said re: the Pot Icon. And Ix, all the bags got resized except the blue ones (for now.)

I miss this style of wood panelling. Can we have it back?

+1 for the wood paneling
