Today's lesson: Always use the proper tool. I wrestled for an hour yesterday trying to the the Gimp to do "text along a curve." It never quite came out right. The few times I got it close, the text looked awful.
This morning I tried a different tool: Inkscape, which is designed to handle vectors and curves. It looked great the first time. Well, it looked right. Now I have to fiddle with it to get the text just right, and then fiddle some more. I might be learning vector illustration by the time this is over, which was planned for the next project, not this one.
