Items you use for pottery tools that aren't technically for pottery?

Trying to out together some gift bags for pottery friends. In addition to some personal gifts, I wanted to add some things that aren't pottery related, but still helpful.

I have 2 of my favorites already... make up sponges that come hard and compressed, but put them in water and they turn into great soft round sponges. I use them like crazy. They are so cheap that it doesn't matter if I lose any, if the dog shreds one, etc.

I am also including a Swedish dish towel. I always have one around when I am handbuilding, painting, carving, etc. Holds the perfect amount of water without being sopping wet. Great for wiping my hands, brushes, cleaning, etc.

Any additional ideas?
