Hello again. OK, looks like that little problem with the text layers is
now solved. Actually, I should have done "flatten image" to start with,
as Gezim Hoxha said. That fixed the problem of the invisible text. Now I
know how to get the text showing up exactly as I want. Two or three more
drafts, and I should have a finished postcard.
I may have other barriers along the way, though. Thanks for all your help.
