It looks great! When you have all the blocks finished, you will probably lay them out in one spot, and be able to sprinkle the different colors as you wish. I really don't like all that white in the modern quilts, but you have just enough of it. It breaks up the other colors.
As for borders. I like Froggy in Texas' idea. But someone else suggested the gray print for the wide outside border. That would be good, too.
Have fun and enjoy the trip. I'm sure it will be loved.
