I was in a situation where I was transforming a bedroom with 2 full closets into my sewing room. I took off the doors to the closets and needed to have shelves installed. While I waited for the shelves I folded the fabrics with the ruler method and placed them in tubs by category ie. flannel, 30's, solids etc. after the shelves were in I just took them out of the tubs and placed in the the order that I wanted. It is so easy to find what I need and it helps me return the fabric to the right place.
