Thanks very much; that got me started at least.  But I'm still kind of 
(My usual state ....)

First off I'm not quite sure how to interpret the table.  The solid 
diamond suit
symbol appears in a row labelled " '12x " and a column labelled " '7 " so I
first conjectured that the corresponding number would (might?) be 127.  But
this gave me an error when I tried it.  I then tried 57, since the solid 
was the next symbol after the solid heart and I had some evidence that the
number for the solid heart was 56.  This indeed worked.

But how can I read off the appropriate number from that table, starting from
scratch, as it were?

One more question:  My code (following the recipe from Paul Isambert)
looks like:

\font\heartfont=favmr7y at 12pt % set your own size here
\newbox\heartbox \setbox\heartbox=\hbox{\heartfont\char"56}
\newbox\dimebox \setbox\dimebox=\hbox{\heartfont\char"57}
$\heartsuit$ \varheart $\diamondsuit$ \vardime

The solid suit symbols come out much much smaller than the "built-in"
silhouette symbols.  Why is that and how can I make them bigger?

Thank you for your patience.
