I like color-coding too! It helps for the rest of it, like the day-to-day things. The system I use for the notecards probably wouldn't make sense to anyone but me. And don't worry, name tags wouldn't really help me anyway. Your blouses are safe.
I've enjoyed them all so far. The latest girl-turned-boy one is really sweet too, if terribly confusing to my brain on principle. I had those things written about him, yes! That's nice.
