Quilter65...I think that any of those would be just great. I like the idea of the red & green blocks alternating in your ribbon border. You can add or not add the additional strip between the ribbon & SNSNS row, it all depends now on how much bigger you want to make your top & if it fits the bed the way you want. It is going to be beautiful!!!!
One thing to remember when your measuring your quilt top on the top of the bed, you need to allow extra for shrinkage, if you haven't pre washed the fabric. I auditioned a quilt top on my king size bed, thinking that the borders I had on it were perfect, well....not the case, it shrunk up about 3" all the way around so they don't line up on the edges of the bed anymore. Lesson learned.
