I wanna put a few shelves up in my closet to display my transformers, Is there anyway to do this with adhesives? Like, an adhesive that would stick to the wall and kind of have a flat top so the shelf could sit on top of it. I already took the measurements of the space and I know exactly the size of shelf that I need to order. I'm thinking I'd use like 4 or 5 adhesives per shelf if I can find them. Any help would be appreciated.
