Thanks! I had read stories of grit in the felt and just didn't have any idea how common it was. It would be silly to scratch up my film if everyone here knows it's a bad idea to use an old one, but it sounds to me like I can clean it up and give it a try. I've got one more roll of HP5+ to go through and then it will be time to try it out.
