It took a long time to arrange the mosaic because I wanted parts of some picture extending into parts of others. Finally I cut enough pictures to fill the page plus two extra squares vertically and one extra horizontally. I overlapped the squares and changed them until I was happy with it.
I cut the squares with the CM trimmer at the edge of the inch mark so they are slightly less than 1".
I tried both black and white pages but the black made the bright colors stand out. (Denny)
