Thanks, Stoker, for the info on Inkscape. I didn't know about that, particularly that it is both effective and free. Through work I was able to get Photoshop on my machine, and several years ago I used that to make 1940s-era road signs as well as billboards and signs for buildings. Now I'm retired, and I don't know how much longer I will have Photoshop. By the time I get around to modeling, in about 6 months, I may no longer have it, so it's nice to know that Inkscape is out there. Thanks for the download link, as well.
