"Curtain" - You can use as shower curtain (like mine), a table cloth (like this gem), or any favorite fabric- ensure the item is easy to wash. **Measure your window ahead of time as sizes vary**
Assembly is quite easy. All you will need to do is hand your curtain rod and then use the clip hooks to hold your "curtain" in place. Make sure each clip is spaced out properly - to ensure that there is no "slouching", like in the photo below!
And, there you have it. A very easy and cheap DIY way to have curtains without the hefty price.
