Many, many metal bookcases. Most are seven feet tall, but have quite a few that are six feet, with some that are five feet, four feet, and three feet. They are all three feet wide and twelve inches deep. Because they are metal, they are light weight, but very sturdy with adjustable shelf heights. They can, of course, be painted very easily to match any décor. Most are black with some that are either tan or beige. You could line a whole garage wall with several of these and have instant garage storage without giving up very much floor space. Very functional - let me know how many you want and what height works for you.
