Well, I haven't uploaded a collage in a while. This is the biggest I've ever done. I had to download and print some stock pictures. Download for a better look - it's huge. Even then the photo doesn't do it justice.
I do my collages just by cutting out pictures and pasting them to a surface, usually cardboard or poster board.
