I saw a similar sign at Hobby Lobby and knew that I could easily recreate it.
I took a piece of scrap wood and painted it white. While it was drying, I printed out a decal using my Cricut that said HAPPY. I also saw some that said HOME and really, you could use any word that you wanted.
After the white paint was dry, I applied the decal and then went over that with Waverly Wax in the color Antique. I removed the decal letters and that was it! Very easy to do.
