I settled on the center configuration and sewed it together. Next decision is whether to have a sashing between the center and the braids.

I vote for sashing. Love the precision and colors.

I like the sashing in between, too. It gives the eye a visual stop between the block and the side strips. The blue diagonal strips against the blue in the log cabin confuses my eyes because it isn't easy to distinguish where my eye is to focus. It is easier to focus on the stop in pattern with the yellow/green strips against the blue in the log cabin.

I love your center. Whether you go with the sashing next to the center logs, or on the outside of your first set of braids will be gorgeous. You have brightened up my day with your beautiful quilt. A thought, if you put the sashing next to the 4 center logs, then you can establish a pattern for separating any more borders you want to add. Then you would add another sashing on the outer edge of the flying Geese Braid, etc.

My two cents worth, I like the sashing. Beautiful piece!

I prefer the first one.
