All of the holes have been filled in and now the colorwash is ready for fine tuning. This is the way I have been working on it but you need to turn your head to the left to see it the way it will finish.
OK, I turned it for you. I didn't realize when I started it that is was sideways and by the time I did notice it, there was too much to move so I just continued. I moved the outer blue edge out one space and then rearranged and filled in the gap because I didn't like the proportion. It could still be at least one row taller but I'll make that decision later. I think it needs more green now that I see it on the computer screen.
This is what my work area looks like as I'm designing. The trays all nest into each other and take up very little space for storage.
