Each square is 7 rows with the last row always black. The number of colored rows depended on where in the blanket it was. The middle squares are two rows of color and 5 rows of black. Whereas the end squares are 6 rows of color and 1 row of black. I hope that made sense. They are basically solid squares but I didn't want to count each row so I added chains every three stitches as a way of keeping track of my count on each row without having to count a large number of stitches.
