Reposting completed Index cards 1-21

I've completed index cards 1-21 of my self-challenge.  I had posted in-progress photos of these before, but am now working to complete both sides of the card at the same time rather than wait until many are half-done.   It was getting far too confusing for me, and probably for others as well, so her we are.  21 cards are complete out of the eventual 730 total cards.  Here are the labeled cards, new numbering reflecting the two side completions.
