I gave the subject of sashing a great deal of thought. At first I thought I would use the lightest value of Pink that I have. After laying out blocks on the Pink I decided that I did not like the result. I then tried a darker value called Carnation. I was still unimpressed.

Then I decided to use a variety of the values for the sashing of each area. I was stumped though about how to impose just a tiny bit of order to that potential chaos until I came up with the idea of outlining some blocks with one sashing color. This would be a great way to even out the values in the color area. Then I had a real lightbulb moment when I realized that if I outlined only blocks in the odd numbered columns that blocks in the even numbered columns would simply fall into place between those blocks and have a variety of sashing colors associated with them. This gave me the perfect combination of order and chaos that I was seeking.

In the layout above keystones have not yet been selected. They will most likely be selected with no attempt to relate to the odd numbered sashing on a block by block basis. The selection will appear random, but it will be made in reference to nearby blocks.

Piecing is well under way. Stay tuned for the big reveal of the upper left corner.
