Ooh - thank you for your help.
I hadn't thought about how long a line I will need for the signatures (in Jean's example Eric Fox or Christopher Hermanstorffer.) Without your suggestion I might have allowed too little space for this.
Thanks for the reminder about the Costello cd. Honestly, I can't remember but I might even have that! (Oh dear . . . brain like a sieve.)
Thanks, also, for your encouraging words. I never have faith in my ability, which is really weird and neurotic of me.
This project is a surprise for a group; no one knows I'm planning to do it. There's no deadline. When I have something to share, I'll post it on FF.
Again, thank you!
