Okay, so I dont really know how to teach you how to make covers, but I guess it's really to do with creativity. To be honest, my covers weren't great and were pretty simple. All I used to do was find a nice large image - one that I could crop easily without it becoming pixelated. I then crop it to the required size, and add the title and authors name in a matching font.
You could read The Makers by Nathaniel, but I'm not sure if that's her username too :/ I think so... On there she also has a link to another 'book' which tells you how to create covers. I checked it out a while back, but it should still be there :)
