Well I'm going totally crazy on this. I never take out guitars from home and anyway if I do I have gig bags to do so. The problem is that I would protect my guitars from dust when they are hanging from the wall or just sitting on the rack. I would like to have something very light just to cover them and possibly something that I can easily wash when it's covered in dust just to non breathe all the dirt they collect. A cover, not a bag. Do you know something like that? Should also be very cheap because I have almost 25 guitars.
