Let's face it! A home is not complete without curtains. A room without a curtain will look so bare that anyone would start to wonder if someone is seriously living in the apartment or house. Thankfully, curtains are plentiful. However, don't make the mistake of buying cheap curtain rods. Cheap rods will often bend, which will make your curtain sag. Go for heavy duty curtain rods to ensure that your curtains will stay in place. If you have heavy curtains, then heavy duty rods are a must.
