I would love to see a picture of your quilt posted on this thread. You may get some really good ideas/thoughts on finishing it. Also, some crayons for color closeness would be helpful.

Thank you for your responses. Here is a picture of the quilt top I have been trying to find additional fabric for the block border. I found the fabric that is lying on top that might look ok. I will cut it smaller (1.5”) to better fit the big blocks.

Just beautiful! Thanks for sharing.

Finding matching fabric
 

I would try taking a picture of the fabric and then using Google's Image Search.
