For the holidays I like to change out as much of my normal décor for holiday décor as possible. It can get expensive but here is an inexpensive way to change out your wall décor.
Inexpensive frames (I got mine at the dollar store)
Subway art printed from the internet
I went on Pinterest and typed in fall printable subway art. The search brought up so many options. I chose a few to print out as 4x6, 5x7, and 8x10 for different walls and rooms in my house. I then printed them in color on my printer and trimmed them to fit the frames. Then just hang them on the wall.
Here is my bathroom wall before:
And here it is after:
Easy, inexpensive, and festive!
