Hello all--Has anyone used blackout fabric for curtains? I finally found some reasonably priced blackout curtains that are the color I was looking for---several of the curtains in my NTM popup were missing as well as the entire valance--so new window coverings are on the agenda. Does the blackout fabric have any insulating factor? It is not called "thermal"--just blackout fabric. We do early spring camping so keeping in the heat is important. I don't want to spend the $ that Joanne's wants for their outdoor fabric and have not been able to find enough in stock of a color or pattern in any retail store to cover all the windows. For anyone that might be interested I found these in a "Brylane Home" catalog. They also have "thermal" curtains but not in the color/patterns I was wanting. They also come in several different lengths and I think I can cut a panel in half horizontally and get two panels from each panel I order--then just have to hem. This catalog has a really good selection of colors to choose from also. I have purchased comforters for beds at home and found their quality comparable to other retail stores.
