I was unsure how this 'self-measure/install' idea was going to work. So on my first order I contacted the company to make sure the blinds really were going to fit. They gave clear instructions and my blinds fit perfectly. On my last order, we were missing valance clips. I contacted the company and the clips arrived at my home in a couple of days. The blinds are improving the appearance of my home one room at a time, and Select Blinds is making it easy and affordable.
