-there is a dehumidifier in there. There is no smell of dampness at all. Do you think it's safe to keep fabric in a basement?-
Your nose doesn't lie. I don't have a basement room right now but it seems many people do and have no problems. My biggest concern would be the fabric so I would probably have a studio down stairs but store the fabric up stairs and just keep what I need down stairs. A big congrats! It is wonderful to have a dedicated space.
