Fun wording for Guest Book?

So I'm doing a guest quilt. Everyone will get a square of fabric and then write their best wishes or whatnot on it and then they'll all be sewed together to create a quilt. Problem is I think everyone would just write "Best wishes" "Good Luck" and the sort. I'm having someone in charge of having people fill in the square but figure if the guest says "I don't know what to write" the igned person can suggest unique ideas. But I don't have any unique ideas...which is where you guys come in! 103 days and counting!
