I have some of the towelettes and have some sponges too. I was running low on the towels and decided to make my own. I bought some Handi Wipes cloths and put quite a bit of soap and a little bit of water in the bottom of a bucket and soaked them. I then folded them in quarters, like a washcloth and laid them out to dry. It did take several days for them to dry, but they work great. When I made my sponges, I took one regular sized sponge and cut it into six squares and did basically the same thing. I put the sponges in those little toiletry containers that I can never figure out what to do with. Then I can carry one into the park in case I need to wash a souvenier cup or something.
