I cant imagine trying to tag each piece of fabric in my stash. I have over 3000 yards of fabric! I have a mental picture that tell me what I have and what I need to pull to work on the next project. When I pull maybe 5 different pieces for a quilt I mark them in the sequence they will be used but that is about it. I do take my stash out every year and air the fabrics out and refold them. It does help to keep them fresh and healthy.
