Well, I finally decided my basic theme for the layout I want. Kept looking, trying to make up my mind. Then I found a wallpaper I'd misplaced and decided it would work as a beginning for my LJ layout. I found one I liked, and can work with...can't customize it if I can't decipher the code.
Anyway, here's a thumbnail of the wallpaper I uploaded, and the beginnings of my new layout theme. Love the colors in this.
