Thanks, Scotty,
I checked, and I don't think that the problem amounted to that. At this point in the process, though, I'm prepared to let any final scaling be addressed by the engraver. I have, however, started re-making the design, since there are a couple of elements that I would like to see improved (namely, the parts that I drew in myself - drawing in Illustrator with the mouse is not advisable for most people, I assume). You would not believe how much easier going it is the second time around...or, on second thought, perhaps you would, having once been a beginner yourself. I am using a couple of different techniques to replace those elements that I didn't particularly like in my first design, including use of one tool in Photoshop to perform one particular function which was difficult in Illustrator. I did run into one hitch with that, but I'm trying to figure that out myself, with the aid of online resources and various books in the public library. If I can't do that, I'll start a new thread and let you know about it...
