I almost never do it the same. I try to do a background paper first, but sometimes I want to put on some elements (especially like...ribbons or more flat elements that lay directly against papers, so I can see how patterns/colors work together when I am adding papers). When I add my photos depends somewhat on if I am finding photos to match a kit, or a kit to match photos (and yes, I must always have them matching - if a photo is b/w, it means it didn't match - lol!). I generally don't delete element layers until I've put something in that place, but I sometimes add extra layers or move them around. Sometimes I do some papers, then some elements, and then the rest of the papers. I'd probably drive someone nuts trying to watch me scrap.
