How could I?

Did you ever have this happen? Apparently I need stronger glasses. I just can't believe I did this but the picture doesn't lie and it gets worse I quilted it and still didn't notice it.

big oops

Oh and of course the sashings are already quilted too. Now what? Do I rip it all out? I am already dreading even the thoughts of that idea. Do I leave it as is? The Amish are said to have a mistake somewhere in their quilts. Maybe I can pretend I'm Amish...  What would you do? Just in case you didn't catch it. See those HST's to the right they are turned in instead of out.
