That is a lovely start to a gorgeous quilt. It looks like you may have to add rows and that could make the quilt look asymmetrical unless you add the rows equally above and below the centre blocks? I guess it would take using half blocks to both top and bottom, to maintain as much symmetry as possible, (if that it what you want) to lengthen it once you have decided on the width. Not sure how it would look. I would be interested to see how you do this. I have done something similar but I had to add rectangular blocks width ways to achieve the length I wanted. I will be looking out for your finished quilt. Best of luck!
