+* Do not mess with fonts as default values of `theme_pomological()`. Created `theme_pomological_fancy()` as wrapper with fancy font defaults instead.

 ## Installation
 
 
 - `theme_pomological()` sets the plot theme to be representative of the paper and styling of the watercolors and includes a paper-colored background, 
 
-- `theme_pomological_nobg()` has the same styling, just with a transparent (or white) background,
+- `theme_pomological_plain()` has the same styling, just with a transparent (or white) background,
 
-- `theme_pomological_plain()` has a white background and doesn't change the font unless requested.
+- `theme_pomological_fancy()` has the paper-colored background and defaults to a fancy handwritten font ([Homemade Apple](https://fonts.google.com/specimen/Homemade+Apple/)).
 
-A handwriting font is needed for the fully authentic pomological look, and I found a few from Google Fonts that fit the bill.

-
-Alternatively, use something like [calligrapher.com](https://www.calligraphr.com/) to create your own handwriting font!
 
 For color and fill scales, **ggpomological** provides `scale_color_pomological()` and `scale_fill_pomological()`.
 
 
 3. Set up continuous scale colors (we'll see...)

+**Warning**: If you don't have the [above fonts](#fonts) installed, you'll get an error message with a lot of warnings when running the below examples. Just replace `theme_pomological("Homemade Apple", 16)` with `theme_pomological()` for the basic theme without the crazy fonts.
