The thing that I love about digital collages is that you can take a very boring picture of say .. leaves and make it more interesting and different.  All you have to do is make a collage background. My collage background is composed of bits of magazines images, and text from books.  I used tissue paper to add some texture in the collage. The collage is scanned on the computer and then layered with the image ( in my case the boring leaves) using any kind of photo shop programme. I use Paint.net for the layering because it is free and it doesn’t give me a headache. ; )
