Because of the way the kids might rummage through the closet, I've taken to just folding and putting everything into a single pillow case for the set. Nice and (mostly) tidy. Even stacks, so long as it's folded on the inside.

For identifying when I take them out of the dryer, someone mentioned that the tags have the sizes. I just checked, and the ones I see don't. They just have code numbers.

There's got to be a better way other than buying all bright red for the kids and everything else for us, because that's what I'm close to doing.
