 \section{The \textsf{FlashCards} Package}
 
-The \textsf{FlashCards} package (and note that it is written in CamelCase) allows you to easily create flashcards and then print them on standard sheet-fed business-card stock which is equivalent to Avery 5371.\footnote{This is for North American business-card stock, which is 8.5 $\times$ 11 inches.} (Avery products are pretty expensive, but I can usually find a less expensive off-brand version elsewhere.)

 \textsf{FlashCards} offers you a limited set of options, which is just fine, since it's more about the information on these cards, rather than how they look. Flash cards don't need to be fancy, but you can do a certain amount of customization with this package.

 \section{The flacards Package}
 
-Next is the \textsf{flacards} package, which is not quite as straighforward as \textsf{FlashCards} because you have to do more work up front to set up the page layout. But this package does offer more options for laying out each card, so if you need a more complex card layout, the trade-off is worth it.

(The class also has two options, \texttt{frontgrid} and \texttt{backgrid} for drawing gridlines around your cards.)
 
 You will probably need to change the default pagelayout options, as the default margins are one centimeter on all sides, and the default card layout is eight rows of three cards each. Because this package already loads the \textsf{geometry} package, you can just add the new margin declarations to your \texttt{documentclass} declaration. For example, to use the Avery 5371 business cards I have on hand, I would use this in my preamble:

 Note that you can also renew any of these commands whenever you want. If you look at that example, you'll see that I threw in a geometry card at the very end.
 
+The \textsf{flacards} package also has a lot of other options for designing your cards, including color options. I could go into them here, since the package documentation doesn't really get into them very much. However, it does include this sentence, which I absolutely love:
