Thank you signs

SO - since we're getting married on/near a golf course, FH and I want to do some cute shots on the course (he's an avid golfer). ONE thought is to have the golf flags that say 'Thank You' on them. I know I saw this somewhere, but I don't know where... Anyone have an idea of where I can get somethign like that? Or any other golf related pictures/thank you ideas? All recommendations welcome!!! Need your creative brains!!

Thank youuuu!!!!
