what fabric to use for cellphone pouch?

[weeefairy.livejournal.com]

I just got a very shiny new smartphone with a touchscreen. I would like to make a pouch for it, and my first thought was felt.
But I only have acrylic felt on hand, won't that scratch the screen on long term? I also have (synthetic) fleece, or I could go to the store and buy wool felt, which one do you guys think is best to use or are they all good?

thanks :)
