While doublet making today, I did some forward planning. A list, in other words.
It's a pretty simple list and it has nothing as elaborate as theme attached to it, but it does cover most of the letters.
K is eluding me at the moment, but I have starting points for all the rest. No guarantees that any will be used, but they'll be a handy fallback.
Knavery, knife, kite, king, Kwik-fit, koala, kedgeree, kangaroo, knee, Kansas, knight, Knossos ...
