When making my husband's lunch one day, I left the top piece of bread off of his sandwich and put the condiments in separate container. On top of the turkey I left a note on heart shaped paper that read, "can't wait till you get home... I LOVE YOU!" Needless to say, when he walked in the door that evening he gave me a kiss and said I love you too.

 

I have also taken dark construction paper and a metallic silver marker and wrote backwards on the paper, "I Love You," and taped it to the wall in front of the bathroom mirror. When my husband turned on the light to take his shower he saw it immediately.
