REQUEST Lampposts inside of the house

Title. I want to make a themed save file, but I don't know how to make custom furniture; could someone help me? Thank you very much!

 

I feel like I need more detail - do you mean you want to make custom lamps with Custom Furniture?

 

Short: Yeah!
Long: I want to have the lampposts (the wood and iron ones you can place outside, that are already in the vanilla game) inside, please! It doesn't really matter if it's CustomFurniture or not.

 

I thought you could already place them inside buildings and houses? I've done it before, albeit it was inside my sheds.

 

This, there should be nothing stopping you from putting anything you can put outside inside - only things that are meant for inside cant be put outside without a mod for it.
