Sew those two strips together into a strip set and then subcut into 4-1/2" strips. The beauty of this is that the sashing strips are cut lengthwise of the grain and, once you sew them onto the block, your sashing strips have almost no stretch and all your blocks fit together so much easier.
That SO makes sense, thanks for the tip! I've only done sashing once, and on an on-point quilt...I have to admit it took a lot of thought to make it work, the old brain isn't as sharp as it used to be, but I also used the block method rather than a separate strip between blocks (by accident, not design, but I'm sticking to it).
