I do the same thing. I have a Canon with a view finder and sometimes I look through the view finder and see where stuff needs to be fixed. I save myself the time and fix it before I snap the picture.
However my biggest help while quilting would probably be my husband. Not only is he REALLY good at picking out fabric but he works really hard so I can quilt whenever I want day or night since I don't have to work. Well I am sure thats the not REAL reason he works so hard. lol but hey it works for us.
