I really like your quilt. It is a refreshing twist on the stack and whack idea. It is amazing how many of us missed it in Bethany Reynolds book. I went to find my book and sure enough-I had missed it. Since you want to enlarge it and since you found more fabric what about making some more squares to use in the enlargement? And, what about a narrow border of a solid or near solid fabric and use the original fabric for the final border? It would certainly create conversation as the viewers would enjoy trying how to figure out how you did it.
