How did I get HERE?

And how am I going to get out of this one?  This is Medallion II from  Jan Stawasz Tatted Treasures.  I'm at the very final ring, but I can't quite get my hand in the right spot to attach the ring to the previous ring (never mind that last folder over join!)  I'm not sure how I was supposed to do this part.  And how do I get out of this mess?  Maybe I have to finger-tat the rest?  I am open to lessons here :)

No wonder I get so frustrated at times - everything is going along quite smoothly, and then when I'm ready to finish I don't know what happened!

EDITED TO ADD:

Ta Da!  The key was walking away for a few minutes.  The lesson here is PATIENCE.  I laid the ring out and looked at how it would connect to the others.  For some reason, something clicked.  Don't ask me how - I can't even explain it.  A few stitches, a join and a look.  Repeat :)  I took a good look before closing the ring - looked good - gritted my teeth and pulled that ring closed.  Whew!  A little blocking and I'm good to stitch this onto my next sewing project.

Finca Thread from FOX

A sidenote about the thread.  Finca thread is pretty when tatted up - it's nice and soft and has a little shine to it.  HOWEVER, if you do much UN-tatting [like me], its softness is not a benefit :)
