How do you know when you are running out of stock? By being smart.

Thread fixture at the college bookstore

Thread fixture (Detail) at the college bookstore

I love the clever little details that make life easier. This fixture has a small and rather clever feature built in. When there are only two spools of thread left a little red tab appears to warn the store staff. And when there is only one spool left the red tab sticks out further and is unmistakable.

Simple, clever, and a real time saver. No need to do a thread inventory every week to make sure you don't run out. One thing that would improve this is having multiple slots for the most popular colours.
