I want to make something like an indoor sliding barn door for the bottom part of my window.
Hello Linda! You could make a barn door for the bottom of your window but then you would have to deal with the barn door hardware across the middle of your window. It might be better to make the barn door cover the whole window.
Here is a DIY interior window shutter that could work well for you: https://themerrythought.com/diy/diy-interior-window-shutters
I have lots of shutters on my windows, but a sliding barn door might be a difficult project and without seeing the particular window hard to advise about.
Hi Linda, this is a great idea, hope it helps you in your project!
Here is how I built a barn door. You could do this window-sized! https://www.charlestoncrafted.com/how-to-build-a-rustic-barn-door/
