You did a great job making this without a pattern to follow! The borders added to each side will look good. When the quilt is on the bed with the "O" centered, the difference in width of the end border and the side borders will look natural and balanced. With one central block making up the largest portion of the quilt, there may be no other way to do this; otherwise, you'd have a square quilt. I think I'd add a series of smaller blocks--maybe 6 or 8 inches each like the central block--in a series down each side. The extra touch of pattern and color would be nice. That may take too much time and work, though.
