The Amusing part is going back over other times, I got confused on different parts, LOL.

In the steps I would start out by saying you are going to create x layers. Then when you say create a layer, name it something specific. The user can change the name, but it makes it easier for them to reference which layer you are making changes too.

At the end of each section, or couple of sections you should list the order the layers should be in, and which ones are hidden etc. There were a couple of times where I couldn't figure out the order from the text and had to move things around until I found what worked.

At the end of the whole tutorial list all the layers, the orders, hidden or unhidden with references to the page where you discussed those layers. I know it is a pain, but it would help immensely. There tend to be a lot of layers and it's very confusing.
