Can you see it?

I was doing so well...trying to keep all of the 9-patch blocks organized and labeled.  My 3 year old grand daughter came to visit and one of us tossed the box that I stored the blocks in while playing around and I had to reorganize the entire thing.  It took a while but I got it done.  So I started on making the chunks again.  Thought I had the top half of the quilt done.  I put the top right hand side up on the design wall.  I was really proud of myself and was looking at it in awe when I spotted it.  I stitched one of the blocks up side down...  Block B5... row one...first block.  At first I thought it was an optical illusion, so I kept looking  from afar and then I got up close and yep...My right side told me to leave it...no one would notice.  My left side (totally anal side) said are you kidding?  Take it down and fix it! What can I say...I am kinda anal that way and it is a gift.  So I fixed it.  The difference is noticeable ... to me it is.  Can you tell the difference?
