Thanks Michel for the comments. I really did work a long time on that one because I kept losing my way and starting over. I know I need to learn layers, so I'll keep trying.
Thanks to sarch99 too for posting about the tutorials. However they are videos, and I have trouble keeping up too. Not because of my English, but because they go so fast, clicking rapidly here and there, that I can't follow what they are doing.
Also, I'm still on dial up internet, and videos take too long to download. Big downloads also rule out for me any challenge or exercise that includes downloading large files.
