I almost always take pictures of the front and back and maybe a close-up of the quilting, but that's as far as I get with documenting what I've done. When I save the picture I give it a name that is descriptive, usually the pattern name. I make sure the time/date on the phone/camera is correct so that when I look at the picture properties I can figure out when the quilt was made. I'm not prolific enough to have trouble remembering what I did with them - LOL!
