I finally made a genuine, 100%, bona fide, seamless, tileable pattern. I'm pretty much pleased with how this very first one turned out.  Since I got tired of looking on peoples Photoshop pages for "free" brushes to download, and seeing all sorts of dire warnings on using their brushes without giving them credit--I decided to learn how to make my own darn brushes.  So now any pattern I make will be made using my own original brushes. Of course I am eventually going to figure out how to make patterns in other ways; I am already working on a few. So I am adding my stuff to the stacks of millions poor TSR is getting inundated with. Thats just fine. I've got lots of original ideas, too, and plenty of time.  :D
