There was a skin tutorial available somewhere one of the members made. Her name is Kitty and it was very helpful to get wet so to speak. I don't know where but I'm hoping someone sees this and guides you to it.
I have been making WB skins for some time now. Click on my name and you will see them. There are to many things to try and tell a person just starting. Best if you can get that tutorial and or just go into SKS (skinstudio) and mess around. After you get a little use to it I would be happy to help with questions. Remember you also need to be able to make many different types of images with a graphic program.
Lets hope someone post a link to that tutorial for you.
