My sewing room is in the basement. Every spring through fall I hang a product called DampRid in my sewing room and throughout this level in our home. DampRid comes in several different forms. It does a wonderful job of keeping my room and everything in it dry as I want it. Too much dampness, I hang two. DampRid is easily available in places like Home Depot, Walmart, Meijer, and even Amazon.com.
