Yes, my best advice..... do not have them sign a quilt that is already made. There is always, some drunk,kid or smart you know what that will mess it up. I have seen it done. Ruined all that time and work by someone who thought it could be undone. Someone on here suggested a "paper frame" around a signature fabric. Tape it down so they can't write outside the line and make lots of extras for mess-ups. That way you can pick and choose the best and ignore the rest.
