I purchased the baskets for my sewing room. I am reorganizing it and the baskets allow me to see what fabrics are in them. I have also segmented the arrangement of the baskets into specific areas of the shelving unit for specific purposes. For example, the tab allows me to designate a basket for uncut fabric for charity projects or for fabrics cut into kits for projects for friends/family. I'll be expanding my use of these baskets soon for tools and other items for my business.
