/diy/ - Do It Yourself

I'm about to make my own closet storage, I've looked into pre-made closet solutions and their either too big, or laughably small. I do however have a fairly small closet..

5 1/2 feet tall (for the room I'm working with), 38 inches wide and 23 inches deep, I'm gonna explain my idea and somebody please tell me if its retarded.

Gonna cut some plywood into lengths that will fit my closet perfectly, then get some smaller lengths of wood, attach them to the insides of the closet and rest plywood on that foundation, I feel this should be a fairly normal installation but can't find a single guide on it.

drew a quick overhead of my idea.. am I missing anything?
