Textured sheers are a great example. It took some careful peering to find the pattern repeat on this sheer, but once you see the repeat, you can't un-see it.
This meant that the board line was a little wobbly in reference to the horizontal stripe.
But by manipulating ever so slightly while stapling to the board, I was able to mitigate the little "frown" and straighten it out.
This client wanted a soft, unstructured look to this sheer roman. I did put clear buckram in the hem to keep the bottom straight, but I kept the rows a little further apart than usual so it would have a little bit of droop but not too much. Not shown: I attached a self-fabric flap to the back of the board to hide the Rollease clutch mechanism from the outside view, and provide shading to avoid seeing the mechanism from the inside.
