I plan to add black strips between the rows. I was running out of daylight when I was taking photos, so I did not do a very good job of lining up the black strips for a photo, but you should be able to get the idea.
I will start cutting the strips for my Challenge Quilt tomorrow. Our quilt block for inspiration this month is the Log Cabin Quilt Block.
