It is a good idea to have another person as an assistant to help you talk things out. After you measure your window switch places and have the other person measure the window again to ensure you both come up with the same measurement.
A little patience can go a long way when measuring and installing your glass sliding door window treatments. Some people find installing window treatments to be a dreadful and frustrating task that they would rather avoid. Allowing your frustration to get the best of you will only make things worse.
The adage you get what you pay for applies. Obviously, everyone has their own personal budget, so buy what you can afford, but try to avoid buying the lowest price blinds because, chances are, they probably won’t last very long.
