That banner? Not made by me, I'm afraid. I write rather than draw really (although I do intend to learn and would have a vague idea on how to do some of that stuff, I suppose...). As it says in my sig, it was made by someone else (over on serebiiforums) - if you look around on forums like these though there should be many 'banner shops' - places where people make you banners. As for how to make them, should be guides on the such on the internet if you look around, I suppose...
