There is a stripe but it's not the same as on the panel.

The only other option - if it's really driving you insane - was what I suggested and then deleted.
To chop off all the left and both(middle) columns, and replace it with a black solid.
There doesn't seem to be any white stripes in the black area between the letters (vertically - ABC to C), so it wouldn't be noticeable.
But then you'd really have to take care to sure it was all nicely lined up when you put it back together.
Again, your quilt.
Your call.
(But if it were mine, I would go with plan A - and maybe use a primary variegated thread on the black background - it hides everything[ATTACH=CONFIG]382420[/ATTACH])
