I have one sister I have not been able to see for several months.  I have asked people in the ward that know her well to write a sentence containing something they like about her.  I am going to paste them on the back of pictures of grapes.  I am going to make a grapevine and decorate her front door when she isn't home.  (She's never home...)  I'm going to tell her in a note that we have been gossiping about her and to look at the fruit and find out what was said and by whom.  "Heard it through the grapevine that....."  (Warning: I know this sister well enough that she will laugh at the gossiping part.  Someone else might need different wording...)
