Begin by chosing the spftware program you are going to use. In my case, I downloaded a demo of PhotoImpact and saw that it was going to be my type of program. You may find other demos online for other graphics/photo editing software. Once you have chosen your program, get to know it - look for tutorials online. Again, in my case, I found Jeri's very helpful PhotoImpact tutorials on how to build a scrapbook page. There are equivalent tutorials available for other programs too, I am sure.
Along side this, look at other peoples' work and look at other tutorials. This should also help you begin your journey!
