I guess my question is what size is the quilt to be? That would determine what size the blocks need to be and if you need to add a design row to either side of the center piece. By doing so the quilt becomes easier to manage and gives you the opportunity to add interest to what might be lost in huge sections of fabric. By adding two same design panels as center panels on either side could add symmetry and size without losing the great design. And yup, paper piece but could be done either way but paper piecing offers the precision. Hope this helps and looks to be a wonderful creative project. Thank you - more pics in future I hope.
