I know, I know... I believe my first thoughts were...
Instructions on how to fold sheets? 
Really Martha?
Is this necessary?
Then I thought of my disorderly linen closet.  The sheets haven't been folded into anything resembling a rectangle since I took them out of their original packaging.  So, what the heck, I gave it a try...
Okay, I can do this... corner into corner... add the 3rd & 4th corner...
And this is where I stopped... because I gotta draw the line somewhere-- Anything more than 4 steps means I have way too much time on my hands.  I quickly folded it into a shape somewhat resembling a rectangle and threw it into the linen closet, proud of my mostly neat and orderly result.  
But if you have more patience than me... look how perfect!
