design decision: 2" (middle) strips

We are assembling 2 strip sets into one long strip and then into a tube, and then cutting the tubes so that when laid out the design is staggered (per the original pattern).
The plain blue strip sets have a strip of "water" going down the middle. We cut them perpendicular in direction compared to how all the other strips are cut, so it will look like water and not an EKG after assembly.
So the water strips are longer than all the other strips, which were cut from selvage to selvage (the factory-cut ends). Although this results in more waste after trimming, it will be worth it to have the effect we want.
