My best organizing tip is when I changed out my bookcases to freestanding shelves on the wall. My sewing room is in the basement and the prior owner had put the downspouts toward the house under the porch. Needless to say I didn't realize the water was seeping into the front wall where my bookcases full of fabrics were. When I moved them, that's when I found out. Now if it leaks (I've replaced all the downspouts and have them going in the correct direction away from the house) so if it leaks the shelves are up off the floors and the fabrics are safe. Also using those comic book boards are a great way to keep your fabrics folded up nicely.
