A reader helped me figure out how to move the photos around, simple, just never explored! If you hover the mouse pointer over the chosen photos in your unsaved collage, a hand appears and you can drag the photos to any arrangement you want. It only works with photos that are the same shape though. Since some of my cobblestone quilts are square and some are rectangular, dragging them to a new spot gives only a partial view. With this colorwash, most of the photos had been trimmed to a similar size.
