I'm sorry I don't have any suggestions for you on the borders for the quilt, but I wanted to say that I think you did a great job of putting the blocks together. I googled images for one block wonder quilts and there are a lot of ideas out there that are more than simply a border of the mother fabric. I saw one where there were blocks to the side of the main images in the mother fabric (what would be your bear, eagle, etc) and then an asymmetrical layout of two narrow borders in a black background. It looked pretty cool.
