Ideally that needs to be the case. But unfortunately I have found too many felt covers?touching the strings. They were either put there by another tuner, or by the customer, who?put?on his/her own hand made cover, that is nothing more than a square piece of felt bought at the fabric store. However, as Paul indicated,?felt absorbs moisture. But this is where I think he and I would disagree. I think the felt then releases the moisture onto the strings. I have observed many grand with felt string covers where the strings are still rusty. But then I have seen grands in homes right next to the ocean, with a ranch hide string cover, two damp chaser rods under the piano, and a full length piano cover over the piano, and the strings still got rusty.
