I'm curious as to how effective my test batch of "char cloth" that I made will be. I made some with paper towel instead of cotton cloth recently. It's nearly pure cellulose, just like cotton, but it's thinner. I was thinking it might work better; it looks pretty similar to normal char cloth. Unfortunately, offhand, I don't have a good way to try it -- no flints at my house. Burns with a nice even, steady wavefront, but I'm not sure of a good way to test how readily it will catch a spark. I've been brushing up a bit on bow drill practice lately, but haven't gotten a coal yet (too much slipping; time to work some more on the bow and spindle), so I can't tell how well it would ignite from that.

Any ideas?
