2D Game Background That Moves Constantly Left

I am trying to make some backgrounds for my 2d game, i have some cloud flipboks that needs move a direction and when they go out of screen come back to screen from opposite direction and a background image that shouldnt move at all. Should i make it in character bp and attach it to spring arm or place them in level. Found some video but all of them are about parallax effects which i dont want to make.
