The outside border was done two blocks at a time. Using the design board I placed two of the same side (there are left and rights) together, so that the blue was contigious. The two orange squares butted together. I had to pin those two together and take it to the sewing machine in order to not get mixed up. With my age and lack of brain power, this was necessary. Then when the two blues lined up, I put it with another doublet and built it up from there. The corners were very easy . Just a blue in the corner.
