Item frame all items mod (help please)

So I have this mod installed and I’m able to place everything as expected. But I’ve seen things where people can change the size of the item or rotate them. Even making the frame invisible but I have no idea how that works. Example, I want to make hanging chains but they are too small. Also is there a way to make the frames upside down? Like the ones you place on ground but being able to place them on the ceiling with it facing down? I really like decorating but I can’t figure this stuff out! lol
