There's a few pictures of quilts made larger. I can't see the pdf at the moment from quiltnNan link but I like where you have the 3D effect on the wallhanging pattern. This picture from google looks beautiful because it has plain fabrics around it. If you do the whole quilt with the block it looks really busy IMHO.
