So I came up with this to help solve this little problem.
It's a magnetic paper clip. I just made some colorful little labels on the computer and laminated it with my "laminator", also known as clear packing tape. Mine is simple and I didn't spend a lot of time on it, but if someone was really creative and had more spare time that I would want to give it, they could make a really cute one with scrapping stuff.
It works pretty well most of the time, but I have to remember to flip it. And then there is the big question of when I set the dishwasher on the timer to go off later, do I put it on clean because they will be clean eventually or do I leave it on dirty so someone doesn't come along and take something out thinking they're clean before the machine kicks on. Like that ever happens. No one but me ever seems to remove anything from the dishwasher.
