A few notes about the construction of Special Delivery (post #4). To spare those whose eyes glaze over at such talk, I’ve put it behind the cut.
The concept: fill a crossword grid using each and every letter from a selected quote—an anagram of the quote, in effect.
The quote I chose had 143 letters, so I used a 13 square x 13 square grid (169 total squares) and symmetrically placed 26 black squares in it to arrive at the necessary 143 white squares.
After symmetrically positioning three themed answers in the grid, I set about filling the rest of the grid. A list of individual letter totals from the quote was constantly checked.
A small supply of S’s and L’s was a bit of a problem. After putting in the three themed entries, only three S’s and two L’s were left to use.
There was a fair amount of starting over and backtracking as I learned how to best manage the list of letters. The one trade-off in making the puzzle was a larger number of “crosswordy” answers than I’d normally use.
In case you’re curious, the last entry to go in the puzzle was 56-Down, which is also the most obscure answer in the puzzle… unless you happen to be into molecular genetics. :-) (The crossing answers and quote leave no doubt as to the correct answer, however.)
