No, you won't be required to invest thousands in new furniture or have to even re-arrange their existing rooms. Instead, decorate their apartment or house with an "I love you" theme.
Consider red and white streamers, balloons (helium filled with bows and ribbons), a Valentine's Day cake, cookies and other treats.
Add love notes (even sticky notes will work!) all over the place, red and white heart confetti, you name it - anything goes!
When your partner enters the room they'll see an instant splash of love, and if possible, there you'll be in the center of it all!
