Been studying your pictures. I think you need to sort your fabrics (I sort mine by color or theme) first, then decide how your are going to utilize your shelves. Could your build a shelf to go on top of the back half of your shelves. If so, then you could put some fabrics in front and some on the shelf on the back half. I don't know if I am making sense to you but think about the spice racks that look like little stair steps.
