The consensus was the pink for the border, so I went with the wisdom of the crowds. I think it was a good choice. I'm already ready for the next project, but I don't know what...maybe a delectable mountains with stripes. I bought the striped fabric a a couple of weeks ago, and want to do something with it.
Here is a mock up. I'm thinking I might have some pink as well as the blue...so that there is some more variety.
