I have many of the larger plastic bins that I store fabric in. I make them with sticky notes that are also taped to the plastic as they tend to fall off otherwise.
I use labels like "baby related fabrics", "pillow case fabrics", or use color schems "blue and yellow patterns", "nature patterns" or use the name of the fabric collection (sometimes using one box to store several fabric collections that I feel will work well together) All of these I have stacked in the closed in the basement bedroom (which has recently had the bed moved upstairs to another bedroom so now it is all mine!!!) I also use the plastic drawer systems on wheels with labels like "cuts under 1 yard", "fat quarters" (which I sort by color), "strips" (which contains misc jelly rolls and strips that I have cut from left over fabrics), "backing fabrics".
