I started a dragon yesterday and I am still working on it. The tutorial I found was for a really gorgeous dragon and I got some great ideas that I plan to use more in my work. But I really learned was what I wanted in a tutorial. Mind you, I've only written one but I have used lots and from a user's perspective, I know what I want in a tutorial. These rules hold for any tutorial not just clay.
1. TAKE LOTS OF PICTURES!!!!
2. Make it printable, so it can be used away from the computer. Don't make the whole tut an image.
3. Remember your audience. Show a finished project in the beginning, giving the size and difficulty.
4. Before you start, give a list of materials. No one wants to get half way through only to find out they don't have what they need. Try to stick with generics if possible.
5. Give know the prep work in advance. Is there a special cane that will be needed, can I make the wings in advance, is there any thing I should know before I start?
6. Keep the steps simple, include a picture for each.
7. Organize your steps. Number them and group the steps if the tutorial is long.
8. Let the reader know how the project will come together. Sometimes that can make all the difference.
9. Tell why you're doing what you're doing. What will make difference and why.
10. Even a great tutorial leaves a sour note if you end it with a list of rules about the tutorial about selling the items, etc.
These are just some ideas for making a tutorial user friendly. Like I said this is from a user's point of view but when I get to the next step, I'm going to keep them in mind.
Next time I'll post a picture of this weekend's dragon.
