Please don't take offense. I suspect Sir Bichur was saying that a bit tongue in cheek. He's one of the most helpful contributors here.
There is no easy or simple answer to your question, however. First off, though, it will help immensely if you have a good understanding of creating and editing images using the various image editors out there. You can do almost everything you need to do a complete skin using plain old MSPaint, but if you want to utilize alpha-blended transparency, you'll need something like Paint Shop Pro, PhotoShop or Paint.NET to create such images, the latter being a free download and a pretty nifty app.
There are some good skinning tutorials available - if you go to the WindowBlinds Gallery on this site (Gallery Tab, then select WindowBlinds from the Gallery list on the upper left) you'll see a right side panel which includes a section on WindowBlinds Tutorials (you may have to scroll down to see it). That's a good place to start.
Beyond that, it is simply a matter of continuous experimentation with SkinStudio & your images, modifying them as needed, sometimes pixel by pixel. There really is no substitute for working with the images & changing/applying the various image attributes in SkinStudio to see how they affect the image display - until you see what the settings do, it's not easy to understand them. Just to keep you on your toes, they're not always internally consistent, either.
Once you get started & you run into things you can't quite figure out, post a question here. Can't guarantee an answer but there are a lot of folks willing to pitch in.
