I love the name Southern Stars..yes you can put the dark teal on out side , but before you do that try a thin boarder of the star color then the wider dark teal , just to see if it don't take the stars away , I like it better if you see the stars first then the other colors.. that is my thought of what I would do , I think maybe I will make one for myself , if you do not mind me copying you , I just love the pattern and colors, it will look great in my bedroom ..thank you for posting it , you did a great job on it..
