Open my vintage thread boxes and you’ll see the same thing, 100wt and specialty thread boxes also all have multiple kinds of bobbins in them.... Means I always know what thread is on any given bobbin and since my bobbins all look very different from each other it works for me. Also helps that I have a gazillion bobbins for each machine. My system’s not ideal, but so far it works better for me than anything else I’ve come up with.

And, I always keep a few empties with each machine.

I cut clear tubing to put around my bobbins so the thread doesn't come off. You can buy one of those cutters designed for plastic tubing at the hardware store- usually they’re in the same aisle as the tubing.
