I just thought that I would share what I came up with for sponge storage. This is one of those plastic bead storage boxes with a lid. I used the tab punch for the color labels and just bent them so the lid will still close. I always have a pile of my sponges and I have to keep washing them because I don't know which ones are dirty and if it was red vs. dark pink or dark blue vs. black. This is much easier and keeps them from rubbing off on clean stuff!
