Hmm..I can't even figure out how layers work. Umm...the picture I'm trying to play with just has a white background, no decorations or anything. How many layers should I use? I read the four tutorials that I found a link to, but I'm so clueless about this. I don't even know how to tell if the changes that I make on one layer are affecting the rest of the set. And I can't tell how whatever I'm playing with is affecting whichever layer I've chosen. I don't know what I'm trying to do, so I don't think I'm asking the right questions.
