that is what I am doing for my sons quilt. you can also increase the size of the carpenters star and then add thin boarders on the side and thicker ones at the top. or just add them to the top and bottom. You could also get another block that looks good with it and add it to the top and bottom. this will add interest. or even do smaller carpenter star blocks on the top and bottom. just play with it after you make the center one. that is what I have had to do. the answer will hit you like a brick when you get it the way you like.
