I always make large bed quilts, king, queen and double square. Generally I make lap quilts and most baby quilts rectangular with the exception of baby floor quilts or quilts to cary babies in. (kind of like recieving blankets) I also prefer utility quilts for in the car, park or on the beach a large square like 65x65. I think it sound like your quilt does not look complete to you eventhough it is done. I have added strips to the top and bottom of quilts in order to achieve the size I wanted, like for extra long twin bed quilts, but never just for the look of it. To me it generally takes away from the look.
