Just because they are indoors does not mean that they should be any less lovely there are so many gorgeous options for indoor backdrops.
If you really love some of the common outdoor options most of them can be transported indoors.
There are a lot more fabric opportunities indoors, such as this complicated beauty.
And you can spice it up with lights (another indoor advantage).
Or you can have a solid wall with flowers.
Or a breezy flower curtain.
The options are really limitless, so dream your dreams, and may you have a happily ever after!
