The next long border also has blue in it--it's the blue and purple colorway. The left short border will the all purples and the final one is the one with some greens in it.
What I am going to do is leave the ends open, which will result in an area in each corner where I can insert 4 more mitered squares. Those will be dark blue, maroon, pink and brown--the four most intense colors. I figure that will tie in the intense bits, and look pretty interesting. I just hope I can remember that and don't just go ahead and pick up across the edges of the long borders. Now that I have written it down, I have hope.
Must run off to work now, and I hope you all have good days.
