I don't know how many blocks you have made. If you've made quite a few, then you are not going to want to start over. Why not pick a fabric and bring each block up to the next inch. If you float your squares on black or solid white, you may not see that some of the sizes of the blocks don't match up. Google Women of the Bible quilt images or follow this link

As you can see, different people have completed the quilt in several different settings.
